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.

Figure 1. Output Waveform
Conditions (25±5°C)
Figure 2. Typical Output Test
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.

ESD Ratings
The VC-800 is capable of meeting the following qualification tests.
Mechanical Shock MIL-STD-883 Method 2002
Mechanical Vibration MIL-STD-883 Method 2007
Solderability MIL-STD-883 Method 2003
Gross and Fine Leak MIL-STD-883 Method 1014
Resistance to Solvents MIL-STD-883 Method 2016
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.
