Description
The CS4364 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 single-ended analog
outputs.
The CS4364 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 CS4364 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,
digital
TV’s,
mixing
consoles,
effects
processors, and sound cards.
This product is available in 48-pin LQFP package in
Commercial (-40°C to +85°C) temperature grade. See
