Integrated Products 1 For free samples & the latest literature or phone 1-800-998-8800 For small orders, phone 1-800-835-8769 1 Connect OUT+ and OUT- to a terminated oscilloscope. 2 Connect IN+ and IN- to a 500mVP-P, 3.2Gbps differential data stream. 3 Remove all shunts. 4 Shunt JU8 to VCC so that there is no inversion of signal polarity. OUTPOL, VCC . Figure 2 shows the jumper diagram for the board. 5 Shunt JU4 connecting R3 = 13k RTH . 6 Shunt JU6 connecting R7 = 10k RLOS . 7 Shunt JU5 connecting pin LOS to DISABLE. 8 Connect TP2 to VCC. 9 Connect the power-supply ground to the GND pad and then connect a +3.3V power supply to the VCC. 10 Observe a limited signal at the output, roughly 0.8Vp-p. 11 Lower the amplitude of the input signal from 500mVp-p to 15mVp-p or less. The output signal is squelched. & '% * NAME JU2, JU3, JU4 JU5 JU6 JU7 JU8 FUNCTION Selects loss of signal assert/deassert level. Shunt to connect the LOS pin to the DISABLE pin Squelch Shunt to connect series resistor from LOS to test point TP2. Make sure TP2 is connected to a positive supply. Disable. Shunting to VCC holds the outputs static. Shunt center pin OUTPOL to VCC for full-swing non-inverted output signal. Shunt to GND to have an inverted full-swing output. Leave open for reduced-amplitude non-inverted output. Connect to for reduced-amplitude inverted output signal. Shunt to connect RSSI output to RSSI resistor R8.
