CrystalClear™ SoundFusion™ PCI Audio Accelerator

PCIVDD[7:0] - PCI Bus Driver Power Supply

(M) pins 50, 39, 31, 21, 8, 100, 94, 86;

(Q) pins 58, 47, 39, 29, 8, 128, 122, 114

PCIVDD pins are the PCI driver power supply pins.

PCIGND[7:0] - PCI Bus Driver Ground Pins

(M) pins 49, 40, 30, 22, 7, 1, 93, 87;

(Q) pins 57, 48, 38, 30, 7, 1, 121, 115

PCIGND pins are the PCI driver ground reference pins.

External Interface Pins

TEST - Test Mode Strap, Input

(M) pin 51; (Q) pin 65

This pin is sampled at reset for test mode entry. If it is high at reset, test mode is enabled. This

pin should normally be pulled to ground in a production design.

EEDAT/GPIO2 - External EEPROM Data / General Purpose I/O Pin 2, I/O Drain

(M) pin 80; (Q) pin 102

Data line for external serial EEPROM containing device configuration data. When used with an

external EEPROM, a 4.7 k

Ω pullup resistor is required. In designs without EEPROM

requirements, this pin can be used as a general purpose input or open drain output.

EECLK/GPOUT - External EEPROM Clock / General Purpose Output Pin, Output

(M) pin 79; (Q) pin 101

Clock line for external serial EEPROM containing device configuration data. In designs

without EEPROM requirements, this pin can be used as a general purpose output pin.

SDIN2/GPIO - Serial Data Input 2 / General Purpose I/O Pin, I/O

(M) pin 66; (Q) pin 88

This dual function pin defaults as a general purpose I/O pin. In non-AC’97 system

configurations, this pin can function as a second stereo digital data input pin if enabled.

VOLUP/XTALI - Volume Up Button / Crystal Input, Input

(M) pin 70; (Q) pin 92

This dual function pin is either the volume up button control input or the crystal oscillator input

pin, depending on system configuration. When a crystal is used, it must designed for

fundamental mode, parallel resonant. This pin may also be used as a general purpose input if its

primary function is not needed.

VOLDN/XTALO - Volume Down Button / Crystal Output, I/O

(M) pin 71; (Q) pin 93

This dual function pin is either the volume down button control input or the crystal oscillator

output pin, depending on system configuration. This pin may also be used as a general purpose

input if its primary function is not needed.
