Description
The CDB4349 evaluation board is an excellent platform
for quickly evaluating the CS4349 24-bit, 24-pin, stereo
D/A converter. Evaluation requires an analog signal an-
alyzer, a digital signal source, a PC for controlling the
CS4349 (only required for Control Port Mode), and a
power 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-compatible audio da-
ta. The evaluation board may also be configured to
accept external timing and data signals for operation in
a user application during system development.
