Description
Vectron’s V-Type Voltage Controlled Crystal
Oscillator (VCXO) is a quartz stabilized square
wave generator with a CMOS output and is
tested at CMOS and TTL (5.0 volt operation)
logic levels.
The V-Type’s small footprint and low profile
make it ideally suitable for PCMCIA applications
as well as any other where size is limited but
performance is required.

1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
2. Figure 1 defines these parameters. Figure 2 illustrates the equivalent five gate TTL load and operating conditions under which
these parameters are tested and specified.
3. Symmetry is defined as (ON TIME/PERIOD with Vs= 1.4 V for TTL and Vs=2.5 V for CMOS, 5 volt operation, and Vs=1.65V
for 3.3 Volt operation.

Absolute Maximum Ratings
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 data sheet. Exposure to absolute maximum ratings for extended periods may
adversely affect device reliability.

Reliability
The V-Type is capable of meeting the following qualification tests.

Handling Precautions
Although ESD protection circuitry has been designed into the the V-Type, proper precautions should be
taken when handling and mounting. VI employs a Human Body Model and a Charged-Device Model
(CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on
the circuit parameters used to define the model. Although no industry wide standard has been adopted
for the CDM, a standard HBM of resistance = 1.5kohms and capacitance = 100pF is widely used and
therefore can be used for comparison purposes.

The V-Type 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 and parameters are listed in the table
below. The contact pads are gold over nickel so lower IR reflow temperatures such as 220°C can be
used (device is backwards compatible with a lead solder assembly).
The V-Type is hermetically sealed so an aqueous wash is not an issue.
