V
FILTER, RSSI, IN+, IN-, CZP, CZN, SQUELCH,
PECL Output Current (OUT+, OUT-, LOS+, LOS-) ............50mA
Differential Voltage Between CZP and CZN..........-1.5V to +1.5V
Differential Voltage Between IN+ and IN- .............-1.5V to +1.5V
+3.0V to +5.5V, 125Mbps to 266Mbps
Limiting Amplifiers with Loss-of-Signal Detector
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
