Description
The CDB4340A/41A evaluation board is an excellent
means for quickly evaluating the CS4340A/41A family of
24-bit, stereo D/A converters. Evaluation requires an an-
alog signal analyzer, a digital signal source, a PC for
controlling the CS4341A and a power supply. Analog
outputs are provided via RCA phono jacks for both
channels.
The CS8414 digital audio receiver I.C. provides the sys-
tem timing necessary to operate the Digital-to-Analog
converters and will accept AES/EBU, S/PDIF, and EIAJ-
340 compatible audio data. The evaluation board may
also be configured to accept external timing signals for
operation
development.
