General Description

The CDB4216 and CDB4218 evaluation boards allow

easy evaluation of the CS4216 and CS4218 audio mul-

timedia codecs. Analog inputs provided include two

BNC line inputs for LIN1 and RIN1, and two

1/4" micro-

phone jacks on the LIN2 and RIN2 lines. Analog

outputs are available on two BNCs.

Digital interfacing is facilitated using one to three of the

buffered ribbon cable headers. All four serial modes of

the CS4216 and all three modes of the CS4218 are

supported using a simple DIP switch which is decoded

to select the proper mode and sub-mode.
