SOLDER TEMPERATURE PROFILE 32MHz+ to 125MHz: 10ms max. (to reach 90% amplitude at 252C) Ageing: 5ppm max. In first year Phase Jitter RMS: <1ps typical Enable Time: 100ms max. Disable Time: 100ns max. Tristate Function (Pad 1): Output (Pad 3) is active if Pad 1 is not connected or a voltage to Pad 1 is HIGH . Output is high impedance when LOW or GROUND is applied to Pad 1. * Frequency stability is inclusive of calibration tolerance at 25C, frequency change due to shock & vibration, 10 supply voltage variation and stability over temperature range. Note: Parameters are measured at ambient temperature of 25C, supply voltage as stated and a load of 15pF CURRENT CONSUMPTION & RISE/FALL TIME Supply Voltage (10%) Frequency Range Rise/Fall +1.8V +2.5V +3.3V +5.0V Time 500kHz to 32MHz 8mA 10mA 15mA 25mA 4ns max. 10mA 14mA 16.5mA 35mA 3ns max. 32MHz+ to 50MHz 40MHz+ to 125MHz 25mA 30mA 35mA 40mA 2ns max.
