Description
The CDB42428 demonstration board is an excellent
means for evaluating the CS424xx family of highly inte-
grated multi-channel CODECs. Evaluation requires an
analog/digital signal source and analyzer, Windows®
compatible computer, and power supplies.
System timing can be provided by an on-board oscillator
or a master clock recovered from the S/PDIF input to the
CS8416. RCA phono jacks are provided for the CS5361
analog inputs and CS424xx analog inputs and outputs.
Digital data I/O is available via RCA phono jacks or opti-
cal connectors to the CS8416 and from the CS8406.
The Windows® software provides a graphical user inter-
face to make configuration of the board easy. The
software communicates through the computer’s parallel
port, and will configure the hardware to allow all features
of the CS424xx to 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.
