Power Supply

1-3

Overview

1.3

Power Supply

The ADSDeSer-50EVM requires two supplies for operation: a +3.3V supply
for the main board power, and a +1.8V to +3.3V supply for the output driver
supply. An onboard regulator su1.5V to power the FPGA.

1.4

Indicators

There are two LEDs on the board. DS1 is used to show the board has power
applied. DS2 is used to indicate when the PROM has finished downloading
the stored program to the FPGA.
