General Description

The CS42406 is a low cost, integrated audio CO-

DEC. The CS42406 performs stereo analog-to-

digital (A/D) conversion and six channels of digital-

to-analog (D/A) conversion of up to 24-bit serial

values at sample rates up to 200 kHz.

The D/A offers a volume control that operates with

a 1 dB step size. It incorporates selectable soft

ramp and zero crossing transition functions to elim-

inate clicks and pops.

The D/A’s integrated digital mixing functions allow

a variety of output configurations ranging from a

channel swap to a stereo-to-mono down-mix.

Standard 50/15

µs de-emphasis is available for

sampling rates of 32, 44.1, and 48 kHz for compat-

ibility with digital audio programs mastered using

the 50/15

µs pre-emphasis technique.

Integrated level translators allow easy interfacing

between the CS42406 and other devices operating

over a wide range of logic levels.

High-pass filters are available for the right and left

channel of the A/D. This allows the A/D to remove

unwanted DC offsets.

The CS42406’s wide dynamic range, negligible

distortion, and low noise make it ideal for applica-

tions such as A/V receivers, DVD receivers, and

set-top box systems.
