Description
The CDB4354 evaluation board is a dedicated platform
designed to facilitate the evaluation of the CS4354 24-
bit, stereo D/A converter. Evaluation requires an analog
signal analyzer, a digital signal source, and a +5 V pow-
er supply. Analog line-level outputs are provided 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 custom user application during system
development.
To accommodate various system configurations, sever-
al hardware controls and resistor population options are
provided. Current sense resistors allow for easy power
calculations during system development.
