VX-705
Description
Vectron’s VX-705 Voltage Controlled Crystal Oscillator (VCXO) is a quartz stabilized square wave generator that can be ordered either with a
CMOS output or complementary LVPECL outputs. The VX-705 uses fundamental crystals resulting in low jitter performance and a monolithic IC
which improves reliability and reduces cost.

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 VX-705 family is capable of meeting the following qualification tests:

Handling Precautions
Although ESD protection circuitry has been designed into the VX-705 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
VX-705 device is hermetically sealed so an
aqueous wash is not an issue.
