CS43122

122 dB, 24-Bit, 192 kHz DAC for Digital Audio

Features

Description

The CS43122 is a complete high performance 24 bit-

192 kHz stereo digital-to-analog conversion system. The

device includes a digital interpolation filter followed by an

oversampled 5 bit delta-sigma modulator which drives

second generation dynamic-element-matching (DEM)

selection logic. The output from the DEM block controls

the input to a multi-element switched capacitor DAC/low-

pass filter, with fully-differential outputs. This multi-bit ar-

chitecture features significantly lower out-of-band noise

and jitter sensitivity than traditional 1-bit designs, and the

advanced second generation DEM guarantees low noise

and distortion at all signal levels.

l 24 Bit Conversion

l Up to 192 kHz Sample Rates

l 122 dB Dynamic Range

l -102 dB THD+N

l Second-Order Dynamic-Element Matching

l Low Clock Jitter Sensitivity

l 102 dB Stop-band attenuation

l Single +5 V supply

l Soft Mute Control

l Digital De-Emphasis for 32, 44.1, and 48 kHz

l External Reference Input

l Pin-compatible with the CS4396

The CS43122 is the optimal D/A converter solution for

any application that requires the highest performance

and best possible sound quality including high-end con-

sumer and professional audio products such as

Universal DVD players, A/V receivers, Outboard D/A

Converters, CD Players, and Mixing Consoles.
