5.9 U15
The CS4334 family members are complete,stereo digital-to-analog output systems including
interpolation,1-bit D/A conversion and output analog filtering in an 8-pin package. The CS4334
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.Theese features are ideal for set-top boxes,DVD
players,SVCD players,and A/V receovers.
