Description
The CDB53L21 evaluation board is an excellent means
for evaluating the CS53L21 ADC. Evaluation requires
an analog audio source, an analog/digital analyzer and
power supplies. Optionally, a Windows PC-compatible
computer may be used to evaluate the CS53L21 in Soft-
ware Mode.
System timing can be provided by the CS53L21 with
supplied master clock, or by using an I/O stake header
with a DSP connected.
RCA phono jacks are provided for the CS53L21 analog
inputs. 1/8” jacks are also available for microphone in-
puts. A digital data output is available from the CS8406
via RCA phono or optical connectors.
The Windows software provides a GUI to make config-
uration of the CDB53L21 easy. The software
communicates through the PC’s serial port or USB port
to configure the control port registers so that all features
of the CS53L21 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.
