EVAL-FT50MHNR Revision A

OVERVIEW
The EVAL-FT50MHNR mini evaluation board
enables evaluation and rapid prototyping of the
Firecomms RedLink® DC-50 MBd non-inverting
transmitter for plastic optic fiber (POF) and
large core glass fiber (200, 400 μm PCS). The
board includes a single RedLink® receiver pre-
mounted onto a simple PCB that allows easy
application of DC power and monitoring of the
output signal via a standard 0.1-inch header.
When paired with a receiver evaluation board
such as the EVAL-FR50MHNR, the EVAL-
FT50MHNR can be used to quickly prototype
and evaluate an optical link.
The unpopulated footprint (J2) for a PCB
mounted SMA connector has been added to
allow a secure connection to lab equipment
such as a Bit Error Rate Tester (BERT).
INITIAL SETUP
1. Connect 3.3/5 V to the Tx VCC header (J1 - Pin 3)
2. Connect GND of a DC power supply to the ground pin of the PCB header (J1 - Pin 2)
3. Connect a signal source to VIN (J1 - Pin 1)
