In or-der to maintain a high level of audio quality, carefulconsideration has been given to component selec-tion and PCB layout. For detailed information onaudio quality measurements in a PC environmentrefer to Personal Computer Audio Quality Mea-surements [6].
The CS4297A and CS4294 are mixed-signal serialaudio codecs compliant with the Intel® Audio Co-dec ’97 Specification [1] (referred to as AC ’97).The CS4297A is compliant with revision 2.1 of theAC ’97 specification, while the CS4294 is AC ’97revision 2.0 compliant. These audio codecs feature20-bit stereo DACs, 18-bit stereo ADCs, and ana-log audio mixers. The CS4297A line-level analogoutputs include: Line Out, Alt Line Out, and MonoOut. The CS4297A line-level analog inputs in-clude: Line In, CD, Video, Aux, Mic1, Mic2, PCBeep, and Phone. The CS4294 line-level analogoutputs include: Line Out and Alt Line Out. TheCS4294 line-level analog inputs include: Line In,CD, Aux, and Mic1. The input signals can be rout-ed to the ADC for recording, or mixed together for
recording and direct playback. The CS4297A aCS4294 have register sets used to control varifeatures such as volume levels, mutes and sigrouting. A high level of audio quality is maintainethroughout the signal chain, exceeding the speccations presented in Chapter 17 of Microsoft’s PC99 System Design Guide [7] (referred to as PC 99).For detailed CS4297A information refer tCS4297A CrystalClear SoundFusion Audio Co-dec ’97 [4]. For detailed CS4294 information referto CS4294 SoundFusion Audio/DockingCodec ’97 [5].
The CS4630 audio controller streams digital audiodata and MIDI over the PCI bus. It also performshardware-controlled signal processing and samplerate conversion. The CS4630 features several pe-ripheral interfaces including MIDI I/O, joystickand game controller input, hardware volume con-trol, and several general purpose I/Os. For detailedCS4630 information refer to CS4630 Crystal-Clear SoundFusion PCI Audio Accelerator [3].

2. SCHEMATIC DESCRIPTIONS
This section describes the CRD4630-10 schematicdesigns shown in figures 1 through 12. These sche-matics are also available in the CMK4630-10 man-ufacturing kit as OrCAD 7.2 files to be used ormodified for individual designs.
2.1 Block Diagram
The block diagram, shown in Figure 2, illustratesschematic section interconnection. The schematicis divided into nine blocks: Analog In, Analog Out,Line In + Headphone Out, CS4294, CS4297A,CS4630, Digital I/O, PCI Bus, and Power.
2.2 Analog In
The CRD4630-10 has three stereo (LINE IN,CD IN, and AUX IN) and two mono (MIC IN andPC SPEAKER IN) analog inputs. See section 2.4.1for LINE IN details.
The 220 pF capacitors located on the MIC input,and the ferrite beads located on the AUX, CD, andPC_BEEP inputs are provided for EMI suppres-sion. These components may be removed if EMCtesting determines they are not required.
All analog inputs except PC_BEEP are AC-cou-pled through a 2.2 µF electrolytic capacitor, mini-mizing the low frequency roll-off. PC_BEEP isAC- coupled through a 0.1 µF capacitor.
2.2.1 CD Input
The CD input, shown in Figure 3, is passed througha divider circuit that does not reduce the voltage.This allows for connection of line-level sources upto 1 Vrms. The divider circuit can be reconfiguredto allow for sources up to 2 Vrms.
The internal CD audio connection, shown inFigure 3, utilizes a pseudo-differential interfacewith CD_COM as the common return path for both
left and right channels. This arrangement reducescommon mode noise picked up along the CD signalpath.
2.2.2 AUX Input
The AUX input, shown in Figure 3, is passedthrough a divider circuit that does not reduce thevoltage. This allows for connection of line-levelsources up to 1 Vrms. The divider circuit can be re-configured to allow for sources up to 2 Vrms.
2.2.3 Microphone Input
The MIC input pre-amp circuit, shown in Figure 4,uses a Motorola MC33078D low noise dual op-amp. One op-amp provides an 18 dB gain stage forthe MIC signal. The other op-amp buffers the phan-tom power supply. Phantom power is derived fromthe +5 V analog supply and buffered by U1A toprovide a maximum of +4.2 V with no load and aminimum of +2.0 V under a 0.8 mA load, as re-quired by PC 99. Also included are 3 dB rolloffs at60 Hz and 15 kHz, as recommended by PC 99.
An alternate, low-cost MIC circuit is also offered.This circuit maintains the PC 99 requirements forboth MIC phantom power and frequency response,without providing any boost. The optional primaryaudio codec, CS4201, contains up to 30 dB of inter-nal microphone boost. If replacing the CS4297Awith a CS4201, external boost is not needed.
Both the CS4297A and CS4294 receive the MICsignal. This allows for several capture options.
2.2.4 PC_BEEP Input
The PC_BEEP input, shown in Figure 3, routes thePC’s beep tones through the CS4297A. A PC BeBypass feature is used that allows system betones to be heard during a system reset or boot-

CRD4630-10
2.3 Analog Out
The CRD4630-10 has three stereo output signalsproviding six channels of audio output(FRONT OUT, SURROUND OUT, andCENTER/LFE OUT).
The FRONT, SURROUND, and CENTER/LFEoutputs, shown in Figure 5, provide 1 Vrms line-level outputs. The 220 pF capacitors provided arefor EMI suppression and may be removed if EMCtesting determines they are not required. Each out-put is AC-coupled through a 10 µF electrolytic ca-pacitor, minimizing the low frequency roll-off.Also provided are 220 kΩ bleed-off resistors,maintaining the audio jacks at 0 V DC.
2.4 Line In + Headphone Out
Audio jack J20, shown in Figure 6, receives eitherthe LINE input or the HEADPHONE output. Setjumpers JP2 and JP3 according to the positions list-ed in Table 1 to determine the functionality of J20.
The 220 pF capacitors provided are for EMI sup-pression. These components may be removed ifEMC testing determines they are not required.
2.4.1 Line Input
The LINE input, shown in Figure 6, is passedthrough a divider circuit reducing the voltage by6 dB allowing connection of line-level sources upto 2 Vrms. This input is AC-coupled through2.2 µF electrolytic capacitors to minimize the lowfrequency roll-off.
2.4.2 Headphone Output
The HEADPHONE output circuit, shown inFigure 6, consists of a Philips TDA1308 low noiseheadphone amplifier connected to theALT_LINE_OUT signal of the CS4297A. The cir-
cuit has a gain of 3 dB and is capable of driving ste-reo headphones with impedances of 32 Ω orgreater. The TDA1308 uses a single ended supplyand is biased with Vref from the CS4297A. R119and R120 are included for short-circuit protection.
An option is provided to bypass the amplifier whenreplacing the CS4297A with a CS4201 audio co-dec. Since the CS4201 contains an integrated head-phone amplifier, an external headphone amplifiercircuit is not needed.
2.5 CS4294
The CS4294, shown in Figure 7, acts as the second-ary audio codec for the CRD4630-10. This audiocodec receives the CRD4630-10 AUX, CD, MIC,and LINE analog inputs. The CS4294 LINE_OUTand ALT_LINE_OUT signals connect respectivelyto the CRD4630-10 SURROUND OUT and CEN-TER/LFE OUT speaker jacks. All the signals areAC-coupled.
The primary audio codec, CS4297A, generates theBIT_CLK AC-Link signal for the CS4294. TheSDATA_IN/ASDIN2 AC-Link signal, created bythe CS4294, is used to communicate with theCS4630. ASDIN2 has a 47 Ω series termination re-sistor to prevent reflections on the AC-Link.
2.6 CS4297A
The CS4297A, shown in Figure 8, acts as the pri-mary audio codec for the CRD4630-10. This audiocodec receives the CRD4630-10 PC_BEEP andMIC analog inputs. The CS4297A LINE_OUT andALT_LINE_OUT signals connect respectively tothe CRD4630-10 FRONT OUT and HEAD-PHONE OUT speaker jacks. All the signals areAC-coupled. Unused analog inputs should be tiedto Vrefout (CS4297A pin 28) or AC-coupled toground through a capacitor to prevent noise.
The BIT_CLK and SDATA_IN/ASDIN AC-Linksignals, created by the CS4297A, are used to com-municate with the CS4630. Both outputs have a

47 Ω series termination resistor to prevent reflec-tions on the AC-Link.
An option is provided to replace the CS4297A witha CS4201 audio codec. In this case, C131 will needto be changed to a 2.2 µF ceramic capacitor.
2.7 CS4630
The CS4630 audio controller, shown in Figure 9,acts as a bridge between the PCI bus and the audiocodecs. Communication between the CS4297A,CS4294, and CS4630 is achieved through the AC-Link signals. The CS4630 generates three AC-Linksignals, SYNC, SDOUT, and RESET#. The SYNCand SDOUT outputs have a 47 Ω series terminationresistor to prevent reflections on the AC-Link.
An external EEPROM, U7, is used to provide aVendor ID and Subsystem ID to the CS4630 atpower-up. The EEPROM is connected to theCS4630 through a data and clock signal, EEDATand EECLK. The EEPROM interface is enabled byconnecting the EEPDIS pin to digital ground.
The CS4630 requires three power supply voltages:+3.3 V, +5 V, and +2.5 V. The PCIVDD pins sup-ply +3.3 V to the CS4630 PCI bus drivers. TheCRYVDD pin supplies +3.3 V to the internal phaselock loop and crystal oscillator. The VDD5REF pinis a +5 V pseudo supply for the PCI bus drivers.This supply enables the PCI interface to support+5 V signals. The CVDD pins supply +2.5 V to thecore stream processor inside the CS4630. All pow-er supply pins have a 0.1 µF decoupling capacitorconnected to digital ground.
Unused inputs and bidirectional pins on theCS4630 are tied to their respective inactive levelsthrough 220 kΩ resistors.
2.8 Digital I/O
The CRD4630-10 digital I/O capabilities includethe Joystick/MIDI interface as well as severalS/PDIF I/O options: S/PDIF optical output, S/PDIFoptical input, and S/PDIF coaxial input.
2.8.1 Joystick/MIDI
The MIDIOUT buffer driver circuit, shown inFigure 10, provides the +5 V TTL compatible out-put on J12. If a +3.3 V compatible output is suffi-cient, remove this circuit and populate R65 tobypass the buffer circuit. Capacitors C71, C78,C81, C84, C86, and C89 are provided for EMI sup-pression and can be removed if EMC testing showsthey are not required. Capacitors C72, C75, C79,C82, C87, C90, C91 and C95 are functional to thejoystick circuitry, as well as provide for EMI sup-pression, and must not be removed.
The Joystick/MIDI output on the CRD4630-10 isnot located on the primary bracket, shown inFigure 18. A short cable is provided to bring theJoystick/MIDI signal to a secondary bracket,shown in Figure 19, when using an analog joystick.If using a USB joystick, the secondary bracket isnot needed.
2.8.2 S/PDIF
The S/PDIF (IEC-958) input and output designs,shown in Figure 11, are compatible with digital in-puts and outputs on consumer devices such as con-sumer stereo receivers and MiniDisc recorders.The CRD4630-10 includes an optical S/PDIF out-put and two S/PDIF input choices, optical and co-axial. As shown in Table 2, jumper JP1 controlswhich input is enabled.

The S/PDIF output operates at a fixed sampling fre-quency of 48 kHz. The S/PDIF inputs are capableof accepting S/PDIF signals with a sample frequen-cy from 22 kHz up to 48 kHz.
The optical S/PDIF input and output use industrystandard TOSLINK, a digital optical transmitterand receiver. The input uses a Toshiba TORX-173digital optical receiver. The output uses a ToshibaTOTX-173 transmitter.
2.9 PCI Bus
The PCI Local Bus Specification, Revision 2.2 [2]requires each unused +3.3 V power pin be connect-ed with an average of 0.01 µF capacitance. Three0.047 µF capacitors in parallel, shown inFigure 12, provide the required capacitance. Anoption to omit the +3.3 V regulator is offered if thisvoltage is known to be provided on the PCI bus.This is done by populating several 0 Ω resistors:R84, R85, and R86.
2.10 Power
The CRD4630-10 has three linear voltage regula-tors, shown in Figure 13, supplying the three re-quired power supply voltages: +5 V, +3.3 V, and+2.5 V. The +5 V supply is used exclusively for theanalog audio circuitry surrounding the CS4297Aand CS4294. The +3.3 V supply is used for the au-dio codecs and controller. The +2.5 V supply, la-beled +CVDD, is used exclusively for the CS4630.
The +3.3 VD and +CVDD digital power signals aresupplied from the +5 V_PCI signal located on the
PCI bus. A LM1117CST-3.3 regulator suppli+3.3 VD while a LM2937IMP-2.5 regulator suplies +CVDD. A separate regulator is recommened for the analog voltage supply to provide gooaudio signal quality. A Motorola MC78M05 reglates the +12 VD supply from the PCI bus down a clean +5 VA analog supply. For the best audperformance, the analog voltage regulator shoube located near the audio codecs.
2.11 Component Selection
Great attention was given to the particular compnents used on the CRD4630-10 board with coperformance, and package selection as the most important factors. Listed are some of the guidelinused in the selection of components:
• No components smaller than 0805 packa
• Single package components; no resistor
• 8-pin devices are in surface mount packa
2.12 EMI Components
A number of capacitors and inductors are into meet EMI compliance tests. These comvalues are suggestions only. Actual componeues will depend on your PC board layout andesign factors. Modify these values as neeorder to achieve an acceptable EMI profile. refer to Printed Circuit Board Design Techniqufor EMC Compliance [8] for further informationEMI compliance techniques.

3. GROUNDING AND LAYOUT
The component layout and signal routing of theCRD4630-10 provides a good model for laying outyour own PCI add-in card. PCI bus based add-incards have explicit requirements on trace lengthsthat are not imposed on motherboard designs.These trace length limits for add-in cards are as fol-lows:
• Maximum trace length for 32-bit signals on 32-bit and 64-bit cards is 1.5 inches.
• Maximum trace lengths for signals on the 64-bit extension are 2 inches.
• Trace length for the PCI CLK signal is2.5 inches ± 0.1 inch.
• The PCI CLK signal must drive only one load.
Please refer to the PCI Local Bus Specification, Re-vision 2.2 [2] for information on routing PCI bussignals on a motherboard.
3.1 Partitioned Voltage and Ground Planes
The CRD4630-10 is partitioned into separate digi-tal and analog sections to prevent digital noise fromaffecting the performance of the analog circuits.The analog section is completely isolated from thedigital section, with each section having their ownseparate ground plane. All analog components,power traces and signal traces are routed over theanalog ground plane. Digital components, powertraces and signal traces are not allowed to crossoverinto the analog section.
The audio codecs, CS4297A and CS4294, are lo-cated over the transition point between the analogand digital ground planes. The pins are arranged onthe audio codecs so that the analog and digital sig-nals are separated from each other. The analog and
digital ground planes must be tied together for tcodec to maintain proper voltage references. Fbest results, the two ground planes are tied togewith a single wide trace between the CS4297A athe CS4294, near their digital ground pins.
Data converters are generally susceptible to noon the crystal pins. In order to reduce couplinnoise on these pins, the area around the crystal its signal traces is filled with copper on the top abottom of the PCB and attached to digital groun
A separate chassis ground provides a refereplane for all the EMI suppression components. Tchassis ground plane is connected to the anaground plane at the external jacks.
3.2 CS4297A/CS4294 Layout Notes
Refer to the CS4297A CrystalClear SoundFu-sion Audio Codec ’97 [4] and the CS4294 Sound-Fusion Audio/Docking Codec ’97 [5] data sheetsfor partitioning and bypass capacitor placement.Pay close attention to bypass capacitors on theREFFLT, AFLT1, AFLT2 pins, and power supplycapacitors.
