Description
The CDB5346 evaluation board is an excellent means
for evaluating the CS5346 ADC. Evaluation requires an
analog signal source and analog/digital analyzer, and
power supplies. A Windows PC-compatible computer
must be used to evaluate the CS5346.
System timing for the I²S, Left-Justified and Right-Justi-
fied interface formats can be provided by the CS5346,
the CS8406, or by the PCM I/O stake header with an ex-
ternal source connected.
RCA phono jacks are provided for the CS5346 analog
inputs and outputs. Digital data input is available via
RCA phono or optical connectors to the CS8406.
The Windows software provides a GUI to make config-
uration of the CDB5346 easy. The software
communicates through the PC’s USB to configure the
control port registers so that all features of the CS5346
can be evaluated. The evaluation board may also be
configured to accept external timing and data signals for
operation in a user application during system
development.
