General Description
The CDB5460AU is an inexpensive tool designed to evaluate
the functionality and performance of the CS5460A. The evalu-
ation board includes an LT1019 voltage reference, a
C8051F320 microcontroller with a USB interface, and firm-
ware. The microcontroller controls the serial communication
between the evaluation board and the PC via the firmware, en-
abling quick and easy access to all of the CS5460A's registers
and functions.
The CDB5460AU includes software for data capture, time do-
main analysis, histogram analysis, and frequency domain
analysis.
