General Description
The CDB5532U is an inexpensive tool designed to eval-
uate the functionality and performance of the CS5532.
The CS5532 datasheet should be read and consulted
when using the CDB5532U evaluation board.
The evaluation board includes a C8051F320 microcon-
troller with a USB interface. The microcontroller controls
the serial communication between the evaluation board
and the PC via the firmware, enabling quick and easy ac-
cess to all of the CS5532’s registers and functions.
The CDB5532U includes software for data capture, time
domain analysis, histogram analysis, and frequency do-
main analysis.
