The purpose of this application note is to describe the evaluation
boards for either the HI3026 or HI3026A 8-bit ultra high
speed analog to digital converters (ADC). The main difference
between the two devices is the maximum conversion speed of
120 MSPS and 140 MSPS respectively. This document will
use HI3026 for both devices. The boards are shipped with the
device soldered onto the PCB. The evaluation board includes
many discrete components along with op amps, buffers, logic
level conversion (ECL to TTL and TTL to ECL) and a 10-bit
D/A converter for reconstructing the output of the HI3026.
After latching the HI3026, input data with a frequency divided
clock, the analog signal can be regenerated by a 10-bit high
speed D/A converter. The latched data can also be extracted
externally via a 24 pin cable connector.
