1. HARDWARE
1.1
The CDB5460AU evaluation board provides a quick means of evaluating the CS5460A power measure-
ment IC. The CDB5460AU evaluation board operates from a single +5 V power supply. The evaluation
board interfaces the CS5460A to a PC via an USB interface. To accomplish this, the board comes
equipped with a C8051F320 microcontroller and a USB interface. Additionally, CDB5460AU GUI software
provides easy access to the internal registers of the CS5460A, and provides a means to display the per-
formance in the time domain or the frequency domain.
1.2
The board is partitioned into two main sections: analog and digital. The analog section consists of the
CS5460A and a precision voltage reference. The digital section consists of the C8051F320 microcontrol-
ler, EEPROM, the hardware test switches, the reset circuitry, and the USB interface. The board also has
a user friendly power supply connection.
