General Description
The CDB5461 is an inexpensive tool designed to evalu-
ate the functionality and performance of the CS5461.
The CS5461 Data Sheet is supplied in conjunction with
the CDB5461 evaluation board.
The evaluation board includes an LT1019 voltage refer-
ence, an 8051 microcontroller, an RS232 transceiver,
and firmware. The 8051 controls the serial communica-
tion between the evaluation board and the PC via the
firmware, enabling quick and easy access to all of the
CS5461’s registers and functions.
The CDB5461 includes software for Data Capture, Time
Domain Analysis, Histogram Analysis, and Frequency
Domain Analysis.
