CS4218 General Description


The CS4218 Stereo Audio Codec is a monolithic CMOS device for computer multimedia, automotive, and portable audio applications. It performs A/D and D/A conversion, filtering, and level setting, creating 4 audio inputs and 2 audio outputs for a digital computer system. The digital interfaces of left and right channels are multiplexed into a single serial data bus with word rates up to 50 kHz per channel.

ADCs and the DACs use delta-sigma modulation with 64X oversampling. The ADCs and DACs include digital decimation filters and output smoothing filters on-chip which eliminate the need for external anti-aliasing filters.

The CS4218 is pin and function compatible with the CS4216 when used in Serial modes 3 and 4. See the Appendix A at the end of this data sheet for details.

I2S is a trademark of Philips.
