General Description
The CDB5534U is an inexpensive tool designed to eval-
uate the functionality and performance of the CS5534.
The CS5534 datasheet should be read and consulted
when using the CDB5534U 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 CS5534’s registers and functions.
The CDB5534U includes software for Data Capture,
Time Domain Analysis, Histogram Analysis, and Fre-
quency Domain Analysis.
