Description
The CDB4391 evaluation board is an excellent means
for quickly evaluating the CS4391 24-bit, stereo D/A con-
verter. Evaluation requires an analog signal analyzer, a
digital signal source, a PC for controlling the CS4391 (for
control port mode only) and a power supply. Analog line
level outputs are provided via RCA phono jacks.
The CS8414 digital audio receiver I.C. provides the sys-
tem timing necessary to operate the Digital-to-Analog
converter and will accept AES/EBU, S/PDIF, and EIAJ-
340 compatible 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.
