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 a test circuit shown in Figure 1.
See Standard Frequencies and Ordering Information tables for more speci c 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.
