Quick Start 1) Connect OUT+, OUT-, LOS+, and LOS- to a 50Ωterminated 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. 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). ________________________________________________________________ Maxim Integrated Products For pricing, delivery, and ordering information, please contact Maxim/Dallas Direct! at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. 1 Evaluates: MAX3964ETP General Description The MAX3964ETP evaluation kit (EV kit) is a fully assembled electrical demonstration kit providing easy evaluation of the MAX3964ETP. The EV kit enables testing of all MAX3964ETP functions. Evaluates: MAX3964ETP MAX3964ETP Evaluation Kit Enabling Squelch Function LOS Threshold Jumper JU2 (SQUELCH) controls the squelch function. To enable squelch, short the jumper. To disable, leave unconnected. 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. Table 1.
