Description
The CDB4353 evaluation board is an excellent means
for quickly evaluating the CS4353 24-bit, high-perfor-
mance stereo D/A converter. Evaluation requires an
analog signal analyzer, a digital signal source, and a
+3.3 V power supply. Analog line-level outputs are pro-
vided via RCA phono jacks.
The CS8416 digital audio receiver IC provides the sys-
tem timing necessary to operate the Digital-to-Analog
converter and will accept S/PDIF and EIAJ-340-com-
patible audio data. The evaluation board may also be
configured to accept external timing and data signals for
operation in a user application during system
development.
The CDB4353 is controlled by switches to select the
digital signal source and configuration options for the
CS4353. Current sense resistors allow for easy power
calculations during system development.
