Description
Using the CDB42L52 evaluation board is an ideal way
to evaluate the CS42L52 CODEC. Use of the board re-
quires an analog/digital signal source, an analyzer and
power supplies. A Windows PC-compatible computer is
also needed in order to configure the CS42L52 and the
board functionality.
System timing can be provided by the CS8416, by the
CS42L52 with supplied master clock, or via an I/O stake
header with a DSP connected.
1/8th inch audio jacks are provided for the CS42L52 an-
alog inputs and HP/Line outputs. Speaker driver
outputs are via Banana jacks. Digital data I/O connec-
tions are via RCA phono or optical connectors to the
CS8416 and CS8406 (S/PDIF Rx and Tx).
The Windows-based software GUI provided makes
configuring the CDB42L52 easy. The software commu-
nicates through the PC’s USB to configure board and
FPGA registers so that all features of the CS42L52 can
be evaluated. The evaluation board may also be con-
figured to accept external timing and data signals for
operation in a user application during system develop-
ment.
