Description
The CDB4398 evaluation board is an excellent means
for quickly evaluating the CS4398 24-bit, high perfor-
mance stereo D/A converter. Evaluation requires an
analog signal analyzer, a digital signal source, a PC for
controlling the CS4398 (stand alone operation is also
available) and a power supply. Analog line level outputs
are provided via RCA phono jacks and balanced XLR.
The CS8414 digital audio receiver I.C. provides the sys-
tem timing necessary to operate the Digital-to-Analog
converter and will accept S/PDIF, and EIAJ-340 compat-
ible audio data. The evaluation board may also be
configured to accept external timing and data signals for
operation in a user application during system
development.
