Description
Vectron’s VC-800 Voltage Controlled Crystal Oscillator
(VCXO) is a quartz stabilized square wave generator
with a CMOS output and is tested at CMOS and TTL
(5 volt operation) logic levels.
The VC-800 is the smallest available VCXO making 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.
4. Load Capacitor will depend on frequency.

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.

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