1. HARDWARE
1.1
The CDB5461AU evaluation board provides a quick means of evaluating the CS5461A Power Meter IC. The
CDB5461AU evaluation board operates from a single +5 V power supply. The evaluation board interfaces the
CS5461A to a PC via an USB interface. To accomplish this, the board comes equipped with a C8051F320 micro-
controller and a USB interface. Additionally, CDB5461AU GUI software provides easy access to the internal
registers of the CS5461A, and provides a means to display the performance in the time domain or frequency domain.
1.2
The board is partitioned into two main sections: analog and digital. The analog section consists of the CS5461A and
a precision voltage reference. The digital section consists of the C8051F320 microcontroller, EEPROM, the hard-
ware test switches, the reset circuitry, and the USB interface. The board also has a user friendly power supply con-
nection.
