Description
The CS5333 is a highly integr ated, 24-b it, 96 kHz audi o
ADC providing stereo ana log-to-di gital conver ters usin g
delta-sigma conversion techniques. This device includes
line level inputs in a 16-pin TSSOP package.
The CS5333 is based on d elta- sigma mo dulati on all owing infinite adjustment of the sample rate between 2 kHz
and 100 kHz simply by changing the master clock
frequency.
The CS5333 operates from a +1.8 V to +3.3 V supply .
These features are ideal fo r set-top boxes, A/V receivers, DVD-karaoke players or any system which requires
optimal performance in a minimum of space.

Notes: 2. Filter response is guaranteed by design.
3. Filter characteristics scale with output sample rate. For output sample rates, Fs, other than 48 kHz, the
0.01 dB passband edge is 0.4535x Fs and the stopband edge is 0.625x Fs.
4. The analog modulator samples the input at 6.144 MHz for an Fs equal to 48 kHz. There is no rejection
of input signals which are multiples of the sampling frequency (n x 6.144 MHz ±21.8 kHz where
n = 0,1,2,3...).
5. Group delay for Fs = 48 kHz, t
= 15/48 kHz = 312µs.
