ORDERING INFORMATION
CDB4245 Evaluation Board
Description
The CDB4245 evaluation board is an excellent means
for evaluating the CS4245 CODEC. Evaluation requires
an analog/digital signal source and analyzer, and power
supplies. A Windows
®
PC compatible computer must be
used to evaluate the CS4245.
System timing for the I²S, Left-Justified and Right-Justi-
fied interface formats can be provided by the CS4245,
the CS8416, the CS8406, or by a PCM I/O stake header
with an external source connected.
RCA phono jacks are provided for the CS4245 analog in-
puts and outputs. Digital data I/O is available via RCA
phono or optical connectors to the CS8416 and CS8406.
The Windows
®
software provides a GUI to make config-
uration of the CDB4245 easy. The software
communicates through the PC’s serial port to configure
the control port registers so that all features of the
CS4245 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.
