LD is an open collector output requiring a 30k ohm pullup resistor to VDD. LD output is logic high under locked condition, logic low for no input at fIN, and for “out-of-lock” condition LD transitions between logic low and logic high at the phase detector frequency.

Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Reliability The FX-500 family is capable of meeting the following qualification tests: Environmental Compliance Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Conditions MIL-STD-883, Method 2002 MIL-STD-883, Method 2007 MIL-STD-883, Method 2003 MIL-STD-883, Method 1014 MIL-STD-883, Method 2016 Handling Precautions Although ESD protection circuitry has been designed into the FX-500 proper precautions should be taken when handling and mounting. VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation.
