SoundFusion^®Audio/Docking Codec ’97 (AMC’97)

FEATURES

DESCRIPTION

n AC ‘97 2.0 compatible

The CS4294 is an AC ‘97 compatible Audio Codec

designed for PC multimedia systems. Using the in-

dustry leading CrystalClear™ delta-sigma and

mixed signal technology, the CS4294 is ideal for

PC 98-compliant desktop, notebook, and enter-

tainment PCs, where high-quality audio features

are required. The CS4294 offers four channels of

D/A and A/D conversion along with analog mixing

and stereo enhancement processing. For multi-

channel audio systems, the CS4294 can provide

four audio channels. The CS4294 provides an en-

hanced digital docking mode for portable

applications by providing a dedicated ADC capture

path from the analog input mixer.

n 20-bit quad output and 18-bit dual stereo input

codec with fixed 48 kHz sampling rate

n Dedicated ADC for enhanced digital docking

n Three analog line-level stereo inputs for connec-

tion from LINE IN, CD, and AUX

n High quality pseudo-differential CD input

n Dual stereo line level output with independent 6-

bit volume control

n 6 General Purpose I/O pins

n Meets or exceeds Microsoft's ^®PC 98 and PC 99

audio performance requirements

n CrystalClear™ Stereo Enhancement
