CS4812

www.DataSheet4U.com CS4812 Fixed Function Multi-Effects Audio Processor Features l DSP Description The CS4812 is a complete audio effects processing system on a chip. This device includes a proprietary 24bit 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. for embedded reverb/effects applications – 24-bit Audio Processing Engine – No External RAM required – Two 24-bit ∆Σ ADCs with 100 dB Dyn.
