SY88973/SY88982/MIC3001-Based

SFP Module

TXRX_982_R1 Evaluation Board

General Description

This evaluation board is an implementation of the

SFP module in a different form factor with on board

faults indicators (LEDs) and a DB-25 connector for

serial communication. The design uses Micrel's

MIC3001 controller, SY88982 (pin compatible with

SY88782 and SY88932) driver, and SY88973 limiting

amplifier.

A picture of the fully bonded board is

shown below.
