12.6.2. General Description

The CS4334 family members are complete, stereo digital-to-analog output systems including
interpolation, 1-bitD/A conversion and output analog filtering in an 8-pinpackage. The CS4334/5/6/7/8/9
support all major audio data interface formats, and the individual devices differ only in the supported
interface format. The CS4334 family is based on delta-sigma modulation, where the modulator output
controls the reference voltage input to an ultra-linear analog low-pass filter. This architecture allows for
infinite adjustment of sample rate between 2 kHz and 100 kHz simply by changing the master clock
frequency. The CS4334 family contains on-chip digital de-emphasis, operates from a single +5V power
supply, and requires minimal support circuitry. These features are ideal for set-top boxes, DVD players,
SVCD players, and A/V receivers.
