CrystalClear™ SoundFusion™ PCI Audio Accelerator

MIDIOUT - MIDI Data Output

(M) pin 63; (Q) pin 77

This is the serial output pin for the internal MIDI port.

CVDD[4:0] - Core Power Supply

(M) pins 68, 64, 61, 12, 19;

(Q) pins 90, 78, 75, 12, 27

Core / Stream Processor power pins.

CGND[4:0] - Core Ground Supply

(M) pins 67, 65, 62, 13, 18;

(Q) pins 89, 79, 76, 13, 26

Core / Stream Processor ground reference pins.

Serial Codec Interface

ABITCLK/SCLK - AC ‘97 Bit Rate Clock / Serial Audio Data Clock, I/O

(M) pin 74; (Q) pin 96

Master timing clock for serial audio data. In AC’97 configurations, this pin is an input which

drives the timing for the AC’97 interface, along with providing the source clock for the PLL. In

CS423x (ISA Codecs) digital link configurations, this pin is an input for the SCLK from the

CS423x DSP port.

ASYNC/FSYNC - AC ‘97 Frame Sync / Serial Audio Frame Sync, O/I

(M) pin 77; (Q) pin 99

Framing clock for serial audio data. In AC’97 configurations, this pin is an output which

indicates the framing for the AC’97 link. In CS423x digital link configurations, this pin is an

input for the FSYNC from the CS423x’s DSP port.

ASDOUT/SDOUT - AC ‘97 Data Out / Serial Audio Data Out, Output

(M) pin 75; (Q) pin 97

Serial audio output data.

ASDIN/SDIN - AC ‘97 Data In / Serial Audio Data In, Input

(M) pin 76; (Q) pin 98

Serial audio input data.

ARST# - AC ‘97 Reset, Output

(M) pin 78; (Q) pin 100

AC’97 link reset pin. This pin also functions as a general purpose reset output in non-AC’97

configurations and will follow RST# pin 82 to ground, but must be forced high by software.
