General Description
The CDB5460A is an inexpensive tool designed to eval-
uate the functionality and performance of the CS5460A.
The CS5460A Data Sheet is supplied in conjunction with
the CDB5460A evaluation board.
The evaluation board includes an LT1019 voltage refer-
ence, an 80C51 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
CS5460A’s registers and functions.
The CDB5460A includes software for Data Capture,
Time Domain Analysis, Histogram Analysis, and Fre-
quency Domain Analysis.
