Introduction
HFBR-0528Z evaluation kit is used to evaluate Avago fiber optic device HFBR-1528Z and HFBR-2528Z. The evaluation kit
is equipped with necessary documents and accessories to ease product evaluation and verification.
Evaluation Kit
HFBR-0528Z contains:
1. Evaluation board
2. HFBR-1528Z and HFBR-2528Z unit
3. POF Cable with V-pin connector
4. HFBR-1528Z/2528Z datasheet
5. AN1080 application note
6. User guide document
Evaluation Board
The basic evaluation board that you receive from Avago incorporates transmitter driver IC SN75451BD, some passive
components, and SMA connectors for the TX input (TXD) and RX output (RXD) port connection. This basic evaluation
board allows you to connect waveform/pattern generator to the TXD with TTL input signal. Receiver’s output signal can
be monitored from the RXD or RXout with oscilloscope by using high impedance setting.
Initial Setup
1. Connect 5 V supply voltage to TXVCC and RXVCC
2. Connect 0 V to TXGND and RXGND
3. Connect TXD to pattern generator output
4. Connect RXout to Oscilloscope with high impedance probe
Bit Error Rate Test Setup
Though the transmitter driver IC’s input and receiver’s output is based on TTL logic (high impedance), the board can be
modified to connect 50 ohm load instrument by doing the following steps:
1. Put R9 (50 ohm resistor).
2. Remove R8 (0 ohm resistor).
3. Put R4 (0 ohm resistor) and R7 (50 ohm resistor).
4. Put U3 (SN74LVC2G125).
5. Connect BVCC (5 V) and BGND (0 V).
