The IT6633 is a three-to-one HDMI v.1.3 active switch that supports a signalling rate of up to 2.25Gbps and the new Deep Color modes. A one-port SINK systems such as flat-panel TVs or LCD projectors could also easily upgrade to three-port by

43

adding an IT6633 at the front. The IT6633 operates in software mode that allows the system to control it via a two-line serial interface, PCSCL/PCSDA. The IT6633 offers two selectable serial programming addresses by PCADR0.

As a active switch, the IT6633 equalizes incoming TMDS data with optimal quality regardless of the incoming signal quality. The highly acclaimed equalization technology of ITE TECH. INC. provides for support of long or low-quality HDMI cables at even the highest speeds. Input terminations of theTMDS inputs and output current levels are both programmable. In addition, the input terminations are disconnectable and hence significantly lower the system power consumption in inactive modes.

The IT6633 embeds an EDID RAM to save the cost of the Three external EDID ROMs. The process of downloading the EDID data into the RAM is simplified by the automatic read-back capability of the

IT6633, minimizing the need of MCU intervention. The IT6633 also embeds three 1K-ohm resisters for HPD signal paths to save external resisters and easy to implement the plug authentication.

The IT6633 also incorporates I2C repeater in its DDC switches, which isolates the DDC capacitances of the two sides of the switch. This allows for longer cable cascading as well as significantly eases the system design to pass Test ID 8-9: DDC/CEC Line Capacitance and Voltage of the HDMI Compliance Test.

The IT6633 also distinguish itself from its peers in that it offers 8kV of Human Body Mode ESD protection to all TMDS high-speed input pins. This saves significant costs in external high-speed ESD diodes, which could be very expensive . Features HDMI active switch, providing superior performance over traditional passive

switches Compliant with HDMI 1.3 and DVI 1.0 standards Serial data rate at up to 2.25Gbps, capable of supporting the following digital

video formats in Deep Color Mode at up to 36 bits (12 bits/color): DTV resolutions: 480i, 576i, 480p, 576p, 720p, 1080i to 1080p PC resolutions: VGA, SVGA, XGA, SXGA to UXGA

Single 3.3V operation Internal AC-coupling at TMDS inputs to cope with uneven intra-pair DC levels of

incoming TMDS signals. Embedded EDID RAM saves external EDID ROM costs Embedded HDP resistors Integrated HPD switches Active port detection by monitoring PWR5V inputs and TMDS input clock. DDC I2C repeater isolates backend DDC capacitive loading from frontend,

44

enhancing the DDC operation compatibility Human Body Mode ESD protection up to 8kV for all TMDS differential input pins Disconnectable input terminations with auto-calibrated impedances Adaptive input equalization supporting long and short cables at the same time Software-mode operation providing flexibility Two possible serial programming device address.. Programmable TMDS output current level Programmable source terminations compliant with HDMI 1.3 standard, providing

optimal source data eyes at high speeds High-impedance TMDS output when disabled Optional backend receiver termination detection for auto powerdown 64-Pin LQFP package RoHS Compliant ( 100% Green available ) 1.5. U6202 (DRV632) DESCRIPTION

The DRV632 is a 2-VRMS pop-free stereo line driver designed to allow the removal of the output

dc-blocking capacitors for reduced component count and cost. The device is ideal for single-supply

electronics where size and cost are critical design parameters

Designed using TI’s patented DirectPath™ technology, The DRV632 is capable of driving 2

VRMS into a 10-kΩ load with 3.3-V supply voltage. The device has differential inputs and uses

external gain-setting resistors to support a gain range of ±1 V/V to ±10 V/V, and gain can be

configured individually for each channel. Line outputs have ±8-kV IEC ESD protection, requiring

just a simple resistor-capacitor ESD protection circuit.The DRV632 has built-in active-mute control

for pop-free audio on/off control.The DRV632 has an external undervoltage detector that mutes the

output when the power supply is removed, ensuring a pop-free shutdown.

Using the DRV632 in audio products can reduce component count considerably compared to

traditional methods of generating a 2-VRMS output. The DRV632 does not require a power supply

greater than 3.3 V to generate its 5.6-Vpp output, nor does it require a split-rail power supply. The

DRV632 integrates its own charge pump to generate a negative supply rail that provides a clean,

pop-free ground-biased 2-VRMS output.

The DRV632 is available in a 14-pin TSSOP.
