General Description
The CDB5550 is an excellent means for quickly evaluat-
ing the functionality and performance of the CS5550 A/D
converter. The CS5550 datasheet is supplied in con-
junction with the CDB5550 evaluation board.
The evaluation board includes a C8051F320 microcon-
troller, a USB interface, drivers, and firmware. The
microcontroller controls the serial communication be-
tween the evaluation board and the PC via the firmware,
enabling quick and easy access to all of the CS5550’s
registers and functions.
The CDB5550 includes software for Data Capture, Time
Domain Analysis, Histogram Analysis, and Frequency
Domain Analysis.
