Today’s competitive environment creates a constant need for higher performance. One common method to optimize system performance involves the use of FET switches (also referred to as signal switches) to provide a high-speed bidirectional bus interface between DSPs, CPUs, industry stan-dard buses, memory and peripherals. The Texas Instruments (TI) signal switch product portfolio consists of digital switches, analog switches and specialty switches that provide high-performance, low-power replacements for standard bus-interface devices when signal buffering (current drive) is not required. Availability in advanced packaging (BGA, QFN and WCSP) also allows TI signal switches to occupy reduced board area in space-constrained applications. TI signal switches optimize next-generation datacom, networking, computing, portable communications and consumer electronic designs by supporting both digital and analog applications.
Analog Switches
TI’s analog switches are designed to pass (or isolate) analog signals (both voltage and current) and support
analog applications such as audio and video data transmission. TI analog switches are available in a wide range of voltages (from 0.8 to 12 V), support fast data through-put (up to 2-GHz bandwidth) and offer low on-resistance and input capacitance for decreased signal distortion and insertion loss. TI analog switches are available in the TI Switch (TS) technology family. The TS product family encompasses a variety of analog switches with different ON resistances, bandwidth, charge injection, and total harmonic distortion to target any application.
当今激烈的竞争环境使得业界对于更高性能的追逐热情持续不减。使用 FET 开关(也被称为“信号开关”)是优化系统性能的一种常用方法,可在 DSP、CPU、业界标准总线、存储器及外设之间提供一个高速双向总线接口。德州仪器 (TI) 的信号开关产品库包括了数字开关、模拟开关和专业开关,当不需要信号缓冲(电流驱动)时,它们可作为标准总线接口器件的高性能、低功耗替代产品。另外,TI 的信号开关还可提供高级封装(BGA、

Analog Switch Overview
Selecting the Right TI Analog Switch
When switches are first considered, a schematic of the ideal switch (similar to the one below) might come to mind. In figure 1, an input signal applied to the left I/O pin (or port) results in an identical output signal at the right I/O pin, and vice versa. However, in the real world, switches are not ideal; and there is always some loss. In the case of clean, properly working mechanical switches, the loss is so miniscule that it hardly bears noting.
Ideal Switch
Like mechanical switches, solid-state switches are not ideal either. In fact, losses associated with solid-state switches can be significant. Why use a switch like this if it is so far from ideal? The answer is convenience and reliability. Mechanical switches are subject to wear out and mechanical reliability issues. Solid-state switches are small, fast, easy-to-use and
easy-to-control and consume relatively little power compared to traditional electrically controlled switches such as relays. The switches referred to here are Complementary Metal-Oxide Semiconductor (CMOS) Field-Effect Transistor (FET) switches.
Digital vs. Analog Signal SwitchesDigital switches are designed to pass (or isolate) digital signal levels and may exhibit the capability to satisfactorily pass analog signals. Examples are CBT and CBTLV switch families.
Analog switches are designed to pass (or isolate) analog signals and often exhibit good digital signal performance as well. One example is TI’s TS technology.
TI offers a wide variety of signal switches, and sometimes the no-menclature can be confused to imply limited functionality for a device or family. However, it should be apparent the most important switch characteris-tic depends on how it is used:
to be passed?
distortion limit for the system?
The following are some things to consider when selecting the right analog switch.
Analog Signal Considerations — For noncharge-pump switches,
amplitude that can be passed without clipping. The gate(s) of the pass transistors must be biased relative to the minimum and maximum values of the expected input voltage range. Some switches allow for biasing from two supplies, making it easy to pass both positive and negative signals. Switches with integrated charge pumps can elevate the gate voltage above V (at the expense of larger I ) and thus pass signals of a magnitude greater than V .
VIH/VIL — Why are these important analog switch considerations? In most applications, the signal switch is con-trolled by the output of a digital source; therefore, the control signal levels, VIH and VIL, must be compatible with that source to ensure proper operation of the switch.

选择合适的 TI 模拟开关
模拟开关系列
理想的开关
当您初次考虑开关产品时,您可能会联想到类似于下图的理想开关示意图。在图1 中,施加至左侧 I/O 引脚(或端口)的输入信号将在右侧的 I/O 引脚上产生相同的输出信号,反之亦然。然而在现实世界中,开关并不是理想的;信号总存在一定的损失。在采用无干扰、正常工作的机械式开关的情况下,这种损失将会小到几乎可以忽略不计的地步。
以下是在选择合适的模拟开关时需要考虑的一些因素。
模拟信号考虑因素
V+ - 对于非充电泵型开关而言,V+ 决定了模拟信号可无削波传导的幅度。传输晶体管的栅极必须相对期望输入电压范围的最小值和最大值施加偏置。某些开关允许从两个电源来施加偏置,因而使其易于传导正信号和负信号。具有集成型充电泵的开关能够将栅极电压提升至高于 V+(代价是需要消耗较大的 I+),从而传导幅度大于 V+ 的信号。
VIH / VIL - 为什么这些参数是重要的模拟开关考虑因素?在大多数应用中,信号开关受控于数字信号源的输出;因此,控制信号电平 VIH 和 VIL 必须与该信号源相兼容,以确保开关的正确操作。与机械式开关一样,固态开关也不是
理想的。事实上,固态开关所造成的损耗有可能相当大。既然开关与理想的情况相去甚远,那为什么还要使用呢?答案是它既方便又可靠。机械式开关容易遭受磨损和机械可靠性问题。固态开关小巧、快速、使用方便、易于控制,而且与传统的电控制
开关(例如继电器)相比,其功耗较低。这里所涉及的开关是互补金属氧化物半导体 (CMOS) 场效应晶体管 (FET) 开关。
数字信号开关与模拟信号开关
数字开关设计用于传导(或隔离)数字信号电平,并有可能具有足以传导模拟信号的能力。例如:CBT 和 CBTLV 开关系列。
模拟开关设计用于传导(或隔离)模拟信号,常常也具有良好的数字信号性能。TI 的 TS 技术即为一例。
TI 提供了多种多样的信号开关,某些情况下命名法可能导致混淆,从而无法清楚地描述某个器件或产品系列的功能限制。不过,有一点应该是显而易见的,即:最为重要的开关特性取决于开关的使用方式:
存在哪些 V+ 电平?
需要传导多大幅度的信号?
系统的最大信号失真限值是多少?

Analog Switch Overview
Selecting the Right TI Analog Switch (Continued)
ON-State Resistance (rON) — Because rON contributes to signal loss and degradation, low-rON tradeoffs must be considered. Non-charge pump switches achieve low rON with large pass transistors. These larger tran-sistors lead to larger die sizes and increased CI/O. This additional channel capacitance can be very significant,
of the switch. Switches using charge-pump technology can achieve low rON and CI/O -cantly higher I .
ON-State Resistance Flatness (rON(flat)) — Specifies the minimum and maxi-mum value of rON over the specified range of conditions. These conditions are typically changes in temperature or supply voltage. Figure 2 is an example of rON(flat).
Typical rON(flat) Measurement
On/Off Capacitance (CON/COFF) — Total switch and load capacitance must be considered because it can affect response time, settling time and fanout limits.
— All CMOS switches have an upper limit to the
matter how low rON and CI/O can be maintained in the chip manufacturing process, they still form an undesired low-pass filter that attenuates the switch output signal.
Sine-Wave Distortion or Total Harmonic Distortion (THD) — These are measure-ments of the linearity of the device. Nonlinearity can be introduced in a number of ways (design, device physics, etc.); but typically the largest contributor is rON, which varies with VI/O for all types of CMOS switches. Having a low rON is important, but
a flat rON over the signal range is as
0 < VI/O < (V – 2 V), n-channel switch-es exhibit very flat rON characteristics; but rON increases very rapidly as VI/O approaches V and VGS decreases. Parallel n-/p-channel switches offer good rON flatness for signal ranges of 0 < VI/O < V , with the best flatness characteristic at the highest recom-mended switch V .
Crosstalk — There are two types of crosstalk to consider:
level of crosstalk is a mea sure of how well decoupled the switch control signal is from the switch output. Due to the parasitic capacitance of CMOS processes, changing the state on the control signal causes noise to appear on the output. In audio applications, this can be a source of the annoying pop that is sometimes heard when switching the unit on or off.
of crosstalk also is a measure of adjacent-channel rejection. As with control-to-output crosstalk, parasitic capacitance can couple the signal on one switch with that on another switch.
OFF Isolation — A measurement of OFF-state switch impedance. It is
with the corresponding channel (NC to COM or NO to COM) in the OFF state.
Feedthrough — This characteristic is related to the ability of the switch to block signals when off. As with crosstalk, parasitic capacitance allows
switch, making it appear to be on.
Charge Injection (Q) — TI specifies enable-to-output crosstalk, and some competitors use this parameter. As with enable-to-output crosstalk, changing the state on the control pin causes a charge to be coupled to the channel of the transistor, introducing signal noise. It is presented in this report for a relative comparison with the competition. A graph of bias voltage vs. charge injection is displayed in figure 3 above.

Break-Before-Make (BBM) Time — Guarantees that two multiplexer paths are never electrically connected when the signal path is changed by the select input. This parameter is measured under a specified range of conditions and by the propagation delay between the output of two ad-jacent analog channels (NC and NO), when the control signal changes state (as shown in figure 4 above).

通态电阻 (rON) - 由于 rON 与信号损失及劣化有关,因此低 rON 的折衷是必须考虑的。非充电泵型开关利用大的传输晶体管来实现低 rON。而此类较大的晶体管会导致芯片尺寸增大,并增加输入/输出电容 (CI/O)。该额外增加的通道电容会造成非常严重的影响,因为它将限制开关的频率响应。采用充电泵技术的开关能够实现低 rON 和低 CI/O,但所需的 I+ 则明显提高。
通态电阻平坦度 (rON(flat)) - 该参数详细说明了在规定的条件范围内 rON 的最小值和最大值。这些条件通常是指温度或电源电压的变化。图 2 是 rON(flat) 的一个例子。
导通/关断电容 (CON / COFF) - 总的开关和负载电容会影响响应时间、稳定时间和扇出限制,因此必须纳入考虑的范畴。
频率响应 - 所有的 CMOS 开关都具有所能传导的频率上限。不管在芯片制造商的处理工艺中能够将 rON 和 CI/O 保持在如何低的数值,阻容耦合仍将形成一个不希望的低通滤波器,从而衰减开关的输出信号。
正弦波失真和总谐波失真 (THD) - 该参数用于衡量器件的线性度。非线性度有可能因多种因素而引入(设计、器件物理特性等等);但通常情况下最大的影响因素是 rON,对于所有类型的 CMOS 开关而言,rON 将随 VI/O 而改变。拥有低 rON 是重要的,但在整个信号范

围内保持平坦的 rON 同样重要。对于 0 < VI/O < (V+ – 2V) 的信号范围,n 沟道开关呈现出非常平坦的 rON 特性;但随着 VI/
O 逐渐逼近 V+、以及 VGS 的下降,rON 将急速增加。并联n / p沟道开关则在 0 < VI/
O < V+ 的信号范围内提供了良好的 rON 平坦度,并在推荐的最高开关电压点 V+ 上具有最佳的平坦度特性。
串扰 - 需要考虑的串扰有两种:
控制(使能)至输出的串扰 - 串扰的级别是对开关控制信号与开关输出之间去耦优劣程度的度量指标。由于 CMOS 处理工艺的寄生电容的原因,改变控制信号的状态将导致在输出端上出现噪声。在音频应用中,这可能是令人反感的劈啪声 (pop) 的来源 - 在音频设备开启和关闭时有时会听到这种声响。
开关之间的串扰 - 串扰的级别也是衡量相邻通道抑制能力的指标。与控制至输出的串扰一样,寄生电容会将源自一个开关上信号耦合至另一个开关的信号。
关断隔离 (OFF Isolation) - 对关断状态下的开关阻抗的度量。该参数以 dB为单位,通过在特定的频率下对处于关断状态的相应通道(NC 至 COM 或 NO至 COM)进行测量而确定。
馈通 (Feedthrough) - 该特性参数与开关在关断状态下阻隔信号的能力有关。与串扰一样,寄生电容可使高频以耦合的方式通过开关,从而使得开关看似处于导通状态。
电荷注入 (Q) - TI 规定了使能至输出串扰,而某些竞争对手则采用这种电荷注入参数。与使能至输出串扰一样,改变控制引脚的状态将导致电荷被耦合至晶体管的通道,从而引起信号噪声。本指南引入该参数旨在与竞争产品进行对比。上方的图 3 示出了偏置
电压与电荷注入的关系曲线。
先断后接 (BBM) 时间 - 当信号通路因选择输入而改变时,确保两个多路复用器的通路之间决不存在电气连接。该参数在规定的条件范围内测量,并通过在控制信号改变状态时测量两个相邻模拟通道(NC 和 NO)的输出之间的传播延迟而确定(如上方的图 4 所示)。
先接后断 (MBB) 时间 - 当信号通路因选择输入而改变时,确保两个多路复用器的通路决不开路。该参数在规定的条件范围内测量,并通过在控制信号改变状态时测量两个相邻模拟通道(NC 和 NO)的输出之间的传播延迟而确定(如上方的图 5 所示)。

Applications
The TS3A26746E is a 2 × 2 cross-point switch that is used to interchange the ground and MIC connections on a headphone connector. The ground switch has an ultra low rON of <0.1 Ω to minimize voltage drop across it, preventingundesired increases in headphone ground reference voltage. The switch state is controlled via the SEL input. When SEL=High, GND is connected to RING2 and MIC is connected to SLEEVE. When SEL=Low, GND is connected to SLEEVE and MIC is connected to RING2. An internal 100k pull-up resistor on the SEL input sets the default state of the switch. This device effectively switches the GND and MIC lines to the appropriate coordinates with minimal signal distortion and power loss.

Applications
The TS3A225E is an audio headset switch device. The device detects the pres-ence of an analog microphone and switches a system analog microphone pin between different connectors in an audio stereo jack. The microphone connection in a stereo connector can be swapped with the ground connection depending on manufacturer. When the device detects a certain configuration, it automatically connects the microphone line to the appropriate pin. The device also reports the presence of an analog microphone on an audio stereo jack.
In some systems, it is desirable to connect the stereo jack pin to ground. The TS3A225E provides two internal low resistance (<100 m) FET switches for ground shorting.

The TS5A26542, TS5A6542, and TS5A12301E are single-pole double-throw (SPDT) analog switches that are designed to operate from 2.25 V to 5.5 V. The TS5A26524 is a dual SPDT, whereas the TS5A6542 and TS5A12301E are single SPDT switches. The devices offer a low ON-state resistance with an excellent channel-to-channel ON-state resistance matching, and the break-before-make feature to prevent signal distortion during the transferring of a signal from one path to another.
These devices have excellent total harmonic distortion (THD) performance and consume very low power. These features make them suitable for portable audio applications. All of the switches can be controlled by 1.8-V signals.

Applications
The TS5A22362, TS5A22364, and TS5A22366 are dual single-pole double-throw (SPDT) analog switches that are designed to operate from 2.25 to 5.5 V. The devices feature negative signal capability that allow signals below ground to pass through the switch without distortion. The break-before-make feature prevents signal distortion during the transferring of a signal from one path to another. Low ON-state resistance, excellent channel-to-channel ON-state resistance matching, and minimal total harmonic distortion (THD) performance make these switches ideal for audio applications.

Applications
The TS3USB3200 is a Double-Pole, Double Throw (DPDT) multiplexer that includes a high-speed Mobile High-Definition Link (MHL) switch and an USB 2.0 high-speed (480Mbps) switches in the same package. Also included is a Single-Pole, Double Throw (SPDT) USB/MHL ID switch for easy information control. These configurations allow the system designer to use a common USB or Micro-USB connector for both MHL video signals and USB data.
The TS3USB3200 has a VCC range of 2.7 V to 4.3 V and also has the option to be powered by VBUS alone without VCC. This device supports Over-Voltage Tolerance (OVT) feature, which allows the I/O pins to withstand over-voltage conditions (up to 5.5 V). The power-off protection feature forces all I/O pins to be in high-impedance mode when power is not present, allowing full isolation of the signals lines under such condition without excessive leakage current. The select pins of TS3USB3200 are compatible with 1.8 V control voltage, allowing them to be directly interfaced with the General Purpose I/O (GPIO) from a mobile processor.
The TS3USB3200 comes with a small 16-pin QFN package with only 2.6 mm x 1.8 mm in size, which makes it a perfect candidate to be used in mobile applications.

TS3USB3200 是一款双刀双掷 (DPDT) 多路复用器,该器件在同一个封装中集成了一
个高速移动高清链接 (MHL) 开关和一个 USB 2.0 高速 (480 Mbps) 开关。另外,此器
件还包括一个用于实现简便信息控制的单刀双掷 (SPDT) USB/MHL ID 开关。这些配
置使得系统设计人员能够为 MHL 视频信号和 USB 数据使用一个普通 USB 或者微
型 USB 连接器。
TS3USB3200 具有一个 2.7 V 至 4.3 V 的 VCC 范围,并具备由 VBUS 单独供电的选项(无
需依靠 VCC)。该器件支持过压容限 (OVT) 特性,此特性使得 I/O 引脚能够耐受过
压情况(高达 5.5V)。当未接入电源时,断电保护特性强制所有 I/O 引脚处于高
阻抗模式,从而在此类情况下实现信号线路的完全隔离,避免产生过大的漏电
流。TS3USB3200 的选择引脚与 1.8 V 控制电压兼容,因而使得它们能够与移动处
理器上的通用 I/O (GPIO) 直接对接。
TS3USB3200 采用小型 16 引脚 QFN 封装(尺寸仅为 2.6 mm x 1.8 mm),这使得此器
件成为移动应用的理想选择。

Applications
The TS3DDR3812 is a 12-channel, 1:2 multiplexer/demultiplexer switch designed for DDR3 applications. It operates from a 3 to 3.6 V supply and offers low and flat ON-state resistance as well as low I/O capacitance which allow it to achieve a typical bandwidth of 1.675 GHz. Channels A0 through A11 are divided into two banks of six bits and are independently controlled via two digital inputs called SEL1 and SEL2. These select inputs control the switch position of each 6-bit DDR3 source and allow them to be routed to one of two end-points. Alternatively, the switch can be used to connect a single endpoint to one of two 6-bit DDR3 sources. For switching 12-bit DDR3 sources, simply connect SEL1 and SEL2 together externally and control all 12 channels with a single GPIO input. An EN input allows the entire chip to be placed into a high-impedance (Hi-Z) state while not in use. These characteristics make the TS3DDR3812 an excellent choice for use in memory, analog/digital video, LAN, and other high-speed signal switching applications.

工作在 3 V 至 3.6 V 电源环境下,可提供低平通态电阻以及低 I/O 电容,从而使
其可达到 1.675 GHz 的典型带宽。通道 A0 至 A11 分成两排,每排 6 位,分别由
两个被称为 SEL1 和 SEL2 的数字输入独立控制。这些选择输入负责控制每个 6 位 DDR3 源的开关位置,并可以使其被路由到两个端点之一。 或者,也可以采用
开关将一个端点与两个 6 位 DDR3 源之一相连。如需对 12 位 DDR3 源进行开关操
作,可以简单地从外部将 SEL1 和 SEL2 连接在一起,并采用单个 GPIO 输入控制
所有 12 个通道。一个 EN 输入可允许在不使用时将整个芯片置于高阻抗 (Hi-Z) 状态。这些特性使得 TS3DDR3812 成为存储器、模拟/数字视频、LAN 及其他高速信
号开关应用的绝佳选择。
