Description
The CS4362 is a complete 6-channel digital-to-analog
system including digital interpolation, fifth-order delta-
sigma digital-to-analog conversion, digital de-empha-
sis, volume control and analog filtering. The advantages
of this architecture include: ideal differential linearity, no
distortion mechanisms due to resistor matching errors,
no linearity drift over time and temperature and a high
tolerance to clock jitter.
The CS4362 is available in a 48-pin LQFP package in
Commercial grade (-10°C to +70°C). The CDB4362
Customer Demonstration Board is also available for de-
vice evaluation and implementation suggestions.
Please see
plete details.
The CS4362 accepts PCM data at sample rates from
4 kHz to 192 kHz, DSD audio data, and operates over a
wide power supply range. These features are ideal for
multi-channel audio systems including DVD players.
SACD players, A/V receivers, digital TV’s, mixing con-
soles, and effects processors.

... PCM Mode Select The CS4362 operates in one of three PCM oversampling modes based on the input sample rate. Mode se- lection is determined by the M3 and M2 pins in Stand-Alone Mode or the FM bits in Control Port Mode. Sin- gle-Speed Mode supports input sample rates kHz and uses a 128x oversampling ratio. Double- Speed Mode supports input sample rates up to 100 kHz and uses an oversampling ratio of 64x ...

... The control port has 2 formats: SPI and I²C, with the CS4362 operating as a slave device. If I²C operation is desired, AD0/CS should be tied to VLC or GND.
