FEATURES

DESCRIPTION



6CH DAC for AC3® 5.1CH purpose.

With high speed PCI V2.1 bus controller and legacy

audio SBPro® DSPemulator,CMI8738 is designed for

PC add-in cards and all-in-one motherboards. No

external CODEC is needed in CMI8738: CMI-8738

supports the legacy audio – SBPRO™, FM

emulator/DLS wavetable music synthesis, and

HRTF 3D positional audio functions. Drivers

support EAX® , Karaoke Key, Echo……functions.

Above all CMI8738 supports PCtel® HSP56 (1789)

interface.

HRTF-based 3D positional audio, supporting

DirectSound™ 3D interface


