Note: Please indicate that you are using the MAX3964ETP when ordering from these suppliers.
Quick Start
1) Connect OUT+, OUT-, LOS+, and LOS- to a 50terminated oscilloscope. 2) Connect a +2V power supply to VCC, a -1.0V to -3.5V power supply to VEE, and the power supply ground to GND. 3) Apply a differential input (2mV P-P to 1.5V P-P ) between IN+ and IN-, at a data rate of 155Mbps. 4) Shunt jumper JU1 in its right-most position to enable R6 and R7. 5) Adjust the LOS threshold with R6 and R7.
Description of Jumpers
Setting the LOS Threshold Resistor
Jumper JU1 controls the resistor used to set the loss-ofsignal threshold. To use supplied potentiometers R6 and R7, shunt the right two pins of JU1. If a set resistor is required, solder a resistor to R9 or R10 and shunt the top two pins of JU1 (for R9), or the left two pins of JU1 (for R10).
*Note: U1 has an exposed pad, which requires it to be solder attached to the circuit board to ensure proper functionality of the part.

Enabling Squelch Function
Jumper JU2 (SQUELCH) controls the squelch function. To enable squelch, short the jumper. To disable, leave unconnected.
LOS Threshold
Test point TP3 (VTH) monitors the output of the internal op amp that sets the LOS threshold voltage.
Description of Test Points
Received Signal-Strength Indicator (RSSI)
Test point TP1 (RSSI) monitors the received signalstrength indicator. This pin is an analog voltage proportional to the input signal amplitude.
