ELECTRICAL CHARACTERISTICS
(VCC = 3.0V to 3.6V, TA = -40°C to +85°C, typical values are at VCC = +3.3V and TA = +25°C, unless otherwise noted.) (Note 1) 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 specificatio ns is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

106.25MHz/212.5MHz/425MHz Clock Oscillators Note 1: Limits at -40°C are guaranteed by design and are not production tested. Note 2: Voltage referenced to ground. Note 3: Outputs are enabled and unloaded. Note 4: When the LVPECL output is disabled, the typical output off current is < 100µA for nominal LVPECL signal levels at the output. Note 5: AC parameters are guaranteed by design and characterization. Note 6: Including oscillator startup time and PLL acquisition time, measured after VCC reaches 3.0V from power-on.
