Description

The CS4365 is a complete 6-channel digital-to-analog

system. This D/A system includes digital de-emphasis,

half-dB step size volume control, ATAPI channel mix-

ing, selectable fast and slow digital interpolation filters

followed by an oversampled, multi-bit delta sigma mod-

ulator which includes mismatch shaping technology that

eliminates distortion due to capacitor mismatch. Follow-

ing this stage is a multi-element switched capacitor

stage and low-pass filter with differential analog

outputs.

The CS4365 also has a proprietary DSD processor

which allows for volume control and 50 kHz on-chip fil-

tering without an intermediate decimation stage. It also

offers an optional path for direct DSD conversion by di-

rectly using the multi-element switched capacitor array.

The CS4365 accepts PCM data at sample rates from

4 kHz to 216 kHz, DSD audio data, and delivers excel-

lent sound quality. These features are ideal for multi-

channel audio systems including SACD players, A/V re-

ceivers,

processors, sound cards and automotive audio

systems.
