Voltage Controlled Crystal Oscillator
Previous Vectron Model VVC4
VV-800
Description
Vectron’s VV-800 Voltage Controlled Crystal Oscillator (VCXO) is a quartz stabilized square wave generator with a CMOS output. The VV-800 uses
fundamental crystals resulting in low jitter performance and a monolithic IC which improves reliability and reduces cost.

1] The power supply should have by-pass capacitors as close to the supply and to ground as possible, for examples 0.1 and 0.01uF
2] Parameters are tested with production test circuit in Figure 1.
3] See Standard Frequencies and Ordering Information tables for more specific information
4] Measured from 20% to 80% of a full output swing (Fig 2).
5] Not tested in production, guaranteed by design, verified at qualification.
6] Tested with Vc = 0.3V to 3.0V unless otherwise stated in part description
7] Broadband Period Jitter measured using Wavecrest SIA3300C, 90K samples.
8] Phase Noise is measured with an Agilent E5052A.
9] The Output is Enabled if the Enable/Disable is left open.

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 OD or Vc is applied before Vcc.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow
simulation. The VV-800 family is capable of meeting the following qualification tests:

Handling Precautions
Although ESD protection circuitry has been designed into the VV-800 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.

The device is qualified to meet the JEDEC standard for
Pb-Free assembly. The temperatures and time intervals
listed are based on the Pb-Free small body requirements.
The VV-800 device is hermetically sealed so an aqueous
wash is not an issue.
