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.
