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^® Windows Sound System standard and will
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.
