1. HARDWARE

1.1 Introduction

The CDB5464U evaluation board provides a convenient means of evaluating the CS5464 power mea-

surement IC. The CDB5464U evaluation board operates from a single +5V power supply. The evaluation

board interfaces the CS5464 to a PC via a USB cable. To accomplish this, the board comes equipped

with a C8051F320 microcontroller and a USB interface. Additionally, the CDB5464U GUI software pro-

vides easy access to the internal registers of the CS5464. The software also provides a means to display

the performance in the time domain or frequency domain.

1.2 Evaluation Board Overview

The board is partitioned into two main sections: analog and digital. The analog section consists of the

CS5464 and a precision voltage reference. The digital section consists of the C8051F320 microcontroller,

EEPROM, the hardware test switches, the reset circuitry, and the USB interface. The board also has a

user friendly power supply connection.
