VC-801
CMOS Crystal Oscillator
Previous Vectron Model VCC4
VC-801
Description
Vectron’s VC-801 Crystal Oscillator (XO) is a quartz stabilized square wave generator with a CMOS output. The VC-801 uses
fundamental or 3rd overtone crystals resulting in very low jitter performance, and a monolithic IC which improves reliability and
reduces cost.

The power supply should have by-pass capacitors as close to the supply and to ground as possible, for example 0.1 and 0.01uF.
Parameters are tested with the test circuit shown in Fig 1.
See Standard Frequencies and Ordering Information tables for more specific information.
Includes initial accuracy, operating temperature, supply voltage, shock and vibration (not under operation) and aging for
±
50 and
±
100ppm options.
Duty Cycle is measured as On Time/Period, see Fig 2.
Broadband Period Jitter measured using Wavecrest SIA3300C, 90K samples, see Application Note for Typical Phase Noise and Jitter Performance.
The Output is Enabled if the Enable/Disable is left open.
Only ±50 and ±100 stability option available for -40/105 °C, -40/125 °C, -55/105 °C and -55/125 °C Operating temperature range.
