5 / 12 page +3.0V to +5.5V, 125Mbps to 266Mbps Limiting Amplifiers with Loss-of-Signal Detector _______________________________________________________________________________________ 5 Pin Description PIN QSOP THIN QFN NAME FUNCTION 1 19 SQUELCH Squelch Input. The squelch function disables the data outputs by forcing OUT- low and OUT+ high during a loss-of-signal condition. Connect to GND or leave unconnected to disable. Connect to VCC to enable squelching. 2 20 VTH Output of Internal Op Amp that Sets Loss-of-Signal Threshold Voltage (Figure 1). Connect a resistor from VTH to INV and from INV to ground (minimum resistance 100k Ω) to program the desired threshold voltage. 31 INV Inverting Input of Internal Op Amp that Sets Loss-of-Signal Threshold Voltage (Figure 1). Connect a resistor from VTH to INV and from INV to ground (minimum resistance 100k Ω) to program the desired threshold voltage. 42 FILTER Filter Output of Full-Wave Logarithmic Detectors (FWDs). The FWD outputs are summed together at FILTER to generate the received-signal-strength indicator (RSSI). Connect a capacitor from FILTER to VCC for proper operation. 53 RSSI Received-Signal-Strength Indicator Output. The analog DC voltage at RSSI indicates the input signal power. The RSSI output is reduced approximately 120mV when LOS+ is asserted. 64 IN- Inverting Data Input 75 IN+ Noninverting Data Input 8— SUB Substrate. Connect to ground. 9, 10 6, 7, 8 GND Ground 11 9 CZP Auto-Zero Capacitor Input. Connect a capacitor between CZP and CZN to determine the offset- correction-loop bandwidth. 12 10 CZN Auto-Zero Capacitor Input. Connect a capacitor between CZP and CZN to determine the offset- correction-loop bandwidth. 13 11 VCCO Output Buffer Supply Voltage. Connect to the same potential as VCC, but filter VCCO and VCC separately. 14 12 OUT+ Noninverting PECL Data Output. Terminate with 50 Ω to (VCC - 2V). 15 13 OUT- Inverting PECL Data Output. Terminate with 50 Ω to (VCC - 2V). 16 14 LOS- Inverting Loss-of-Signal Output. LOS- is asserted low when input power drops below the LOS threshold. For the MAX3964A/MAX3968, this pin is PECL compatible and should be terminated with 50 Ω to (VCC - 2V). For the MAX3965, this output is TTL compatible and does not require termination. 17 15 LOS+ Noninverting Loss-of-Signal Output. LOS+ is asserted high when input power drops below the LOS threshold. For the MAX3964A/MAX3968, this pin is PECL compatible and should be terminated with 50 Ω to (VCC - 2V). For the MAX3965, this output is TTL compatible and does not require termination. VCCO MAX3964A/MAX3968: This pin can be left open or connected to the positive supply. 18 16 GNDO MAX3965: This pin must be connected to ground. 19, 20 17, 18 VCC +3.0V to +5.5V Supply Voltage —EP Exposed Pad Connect the exposed pad to board ground for optional electrical and thermal performance. |
