EVAL-FR10DHIR Revision A

OVERVIEW
The EVAL-FR10DHIR mini evaluation board
enables evaluation and rapid prototyping of the
Firecomms RedLink® DC-10 MBd inverting
receiver 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 transmitter evaluation
board such as the EVAL-FT10MHNR, the EVAL-
FR10DHIR 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 Rx VCC header (J1 - Pin 1)
2. Connect GND of a DC power supply to the ground pin of the PCB header (J1 - Pin 2)
3. To monitor Vout, connect to an oscilloscope channel with a 1 MΩ high impedance probe (J1 - Pin 3)
