General Description
The CDB5463U is an inexpensive tool designed to evaluate
the functionality and performance of the CS5463 analog-to-dig-
ital converter (ADC). The evaluation board includes an LT1019
voltage reference, a C8051F320 microcontroller with a USB in-
terface, and firmware. The microcontroller controls the serial
communication between the evaluation board and the PC via
the firmware, enabling quick and easy access to all of
theCS5463's registers and functions.
The CDB5463U includes software for data capture, time do-
main analysis, histogram analysis, and frequency domain
analysis.
