Description
The CS4812 is a complete audio effects processing
system on a chip. This device includes a proprietary 24-
bit audio processing engine with considerable on-chip
RAM, two ADCs and two DACs. A full-featured serial
control port allows interfacing to an external host
microcontroller. Other features such as single +5V
operation simplify system design.
The CS4812, combined with Crystal effects firmware, is
the ideal solution for a variety of effects processing
applications where user parameter control is desired.
The Crystal effects firmware provides a messaging
protocol for the serial control port that allows an external
microcontroller to have real-time parameter control over
the audio effects. The complete processor and effects
solution may be evaluated with the CDB4812
demonstration board. The CDB4812 demonstrates a
host of mono electric guitar effects including a digital
spring reverb, delay, chorus, flange and tremolo with
parameter adjustment capability. Please refer to AN195
for more information on application firmware for the
CS4812.
