CDB4344 Evaluation Board for CS4344 Features Description The CDB4344 evaluation board is an excellent means z Demonstrates recommended layout and for quickly evaluating the CS4344 24-bit, 10 pin stereo grounding arrangements D/A converter. Evaluation requires an analog signal an- z CS8416 receives S/PDIF, & EIAJ-340 alyzer, a digital signal source, and a power supply. compatible digital audio Analog line level outputs are provided via RCA phono z Header for external PCM audio jacks. z Requires only a digital signal source and The CS8416 digital audio receiver I.C. provides the sys- power supplies for a complete Digital-to- tem timing necessary to operate the Digital-to-Analog Analog-Converter system 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.
