Description
Vectron’s VCC1 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating off either a 1.8, 2.5, 3.3 or a 5.0 volt supply. The VCC1 is uses fundamental or 3rd overtone crystals resulting in low jitter performance, typically 0.5pS rms in the 12 kHz to 20MHz band. Also a monolithic IC, which improves reliability and reduces cost , is hermitically sealed. fo Output Buffer / Disable

When the E/D is set to a logic low, the oscillator stops and the output is in a high impedance state. This helps reduce power consumption as well as facilitating boa rd testing and troubleshooting. TriState Functional Description Under normal operation the Tristate is left open or set to a logic high state. When the Tri -State is set to a logic low, the oscillator remains active but the output buffer is in a high impedance state. This helps facilitate board testing and troubleshooting.
