General Description

The SY88353BL evaluation board enables fast and

thorough evaluation of the SY88353BL post amplifier.

It provides a unique pin (VTHP) at which a variable

DC signal can be applied to adjust the output signal

crossing from 20 to 80%. This feature eliminates input

DC offsets in DC-coupled applications, minimizes

jitter caused by duty cycle distortion, and ultimately

optimizes bit error rate (BER) performance. The

board is an easy-to-use, single-supply design,

designed to be driven by a high-speed, pattern

generator.

The SY88353BL evaluation board is intended to

terminate to a 50 scope and provides for simple

user adjustability of the LOS threshold through the

adjustment of an on-board potentiometer as well as

simple evaluation of the output signal crossings.

All data sheets and support documentation can be

found on Micrel’s web site at: www.micrel.com.
