... 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 ...

... VCC6-Q/R Series, 2.5 and 3.3v PECL Crystal Oscillator IR Reflow and Suggested Pad Size Layout The VCC6 has been qualified to meet the JEDEC standard for Pb-Free assembly. The temperatures and time intervals listed are based on the Pb-Free small body requirements and maximum parameters are listed in Table 6, lower temperatures are also acceptable. The VCC6 is hermetically sealed so an aqueous wash is not an issue. Frequencies > ...
