3. HCS Cable with SMA connector
4. HFBR-1506AMZ /2506AMZ datasheet
5. 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 5V supply voltage to TXVCC and RXVCC
2. Connect 0V 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 50ohm load instrument by doing the following steps:
1. Put R2 (50 ohm resistor).
2. Remove R3 (0 ohm resistor).
3. Put R4 (0 ohm resistor) and R7 (50 ohm resistor).
4. Put U3 (SN74LVC2G125).
5. Connect BVCC (5V) and BGND (0V).
