VECTRON VC-820

VC-820
CMOS Crystal Oscillator
VC-820
Description
Vectron’s VC-820 Crystal Oscillator (XO) is a quartz stabilized square wave generator with a CMOS output. The VC-820 uses a fundamental or a 3rd
overtone crystal, oscillating in a fundamental tone, 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 Figure 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.
Duty Cycle is measured as On Time/Period, see Fig 2.
Broadband Period Jitter measured using Wavecrest SIA3300C, 90K samples.
The Output is Enabled if the Enable/Disable is left open.

Although ESD protection circuitry has been designed into the VC-820 proper precautions should be taken when handling
and mounting. VI employs a human body model (HBM) and a charged device model (CDM) for ESD susceptibility testing
and design protection evaluation.

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not
implied at these or any other conditions in excess of conditions represented in the operational sections of this datasheet.
Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Permanent damage is
also possible if E/D is applied before VDD.

The VC-820 is qualified to meet the
JEDEC standard for Pb-Free assembly.
The temperatures and time intervals
listed are based on the Pb-Free small
