Description
The VS-500A is a SAW based voltage controlled
oscillator that operates at the fundamental frequency of
the internal SAW filter. This resonator is a high-Q quartz
device that enables the circuit to achieve low phase
jitter performance over a wide operating temperature
range. The oscillator is housed in a hermetically sealed
J-lead surface mount package offered on tape and reel.
It has an output disable to facilitate on-board testing.
and data retiming applications

... VS-500A Voltage Controlled SAW Oscillator Pin Information Table 1. Pin Function Pin Symbol GND 4 Output 5 COutput setting OD low, the outputs are disabled and OUT is held high while Complementary OUT is held low. The threshold for Output Disable is 1.4V above pin 3. Output Disable should not be driven above mid supply and during normal operation, should be left floating (use with an open collector or 3-State gate for interfacing with standard logic) ...
