Description
The CDB5351 evaluation board is an excellent means
for quickly evaluating the CS5351 24-bit, stereo A/D con-
verter. Evaluation requires a digital signal analyzer, an
analog signal source, and a power supply.
Also included is a CS8406 digital audio interface trans-
mitter
which
generates
S/PDIF,
and
EIAJ-340
compatible audio data. The digital audio data is available
via RCA phono and optical connectors.
