... Includes calibration tolerance, operating temperature, supply voltage variations, aging (40 degreesC/10 years) and shock and vibration (not under operation). 5. Measurements made on a VCC6-QAB-155M520 using an Agilent E5052A for phase noise and LeCroy 8600, 25K samples for jitter. 6. Output will be enabled if Enable/Disable is left open. The pull resistor changes to a higher value, operating in a “power saving mode” when Enable/Disable is set to a logic 0 ...

... VCC6-Q/R Series, 2.5 and 3.3v PECL Crystal Oscillator Terminating PECL Outputs The VCC6 incorporates a standard PECL output scheme, which are un-terminated emitters as shown in Figure 5. There are numerous application notes on terminating and interfacing PECL logic and the two most common methods are a single resistor to ground, Figure 6, and a pull-up/pull-down scheme as shown in Figure 7 ...

... VCC6-Q/R Series, 2.5 and 3.3v PECL Crystal Oscillator Enable/Disable Functional Description Under normal operation the Enable/Disable is left open, or set to a logic high state, and the VCC6 is in oscillation mode and outputs are enabled (active). When the E/D is set to a logic low, the oscillator stops and the both the output and complementary outputs are in a high impedance state ...
