DESCRIPTION

The CS4239 is a single chip multimedia audio system

that is a pin-compatible upgrade to the CS423xB for

many designs. The product includes an integrated FM

synthesizer and a Plug-and-Play interface. In addition,

the CS4239 includes hardware master volume control

pins as well as extensive power management and 3D

sound technology. The CS4239 adds a Zoom-Video

asynchronous digital serial interface to the industry

standard CS423xB. The CS4239 is compatible with the

Microsoft

run software written to the Sound Blaster and Sound

Blaster Pro interfaces. The CS4239 is fully compliant

with Microsoft’s PC ’97 and PC ’98 audio requirements.
