Description
The CDB5505/5506/5507/5508 is a circuit board de-
signed to provide quick evaluation of the CS5505/6/7/8
series of A/D converters. The board can be configured to
evaluate the CS5505/6/7/8 in either SSC (Synchronous
Self-Clocking) or SEC (Synchronous External-Clocking)
serial port mode.
The board allows access to all of the digital interface pins
of the CS5505/6/7/8 chip.
