Description
The F-Type Voltage Controlled Crystal Oscillator
(VCXO) is used in a phase lock loop applications
including clock recovery and frequency translation
applications. The metal package is grounded for
improved EMI performance.

2. A 0.1
F low frequency tantalum bypass capacitor in parallel with a 0.01
F high frequency ceramic capacitor is recommended. Both should be located as close to the FTU-Type bias pin as is practical

Handling Precautions
Although protection circuitry has been designed into this
device, proper precautions should be taken to avoid exposure
to electrostatic discharge (ESD) during handling and mounting.
VTI employs a human-body model (HBM) and a charged-
device model (CDM) for ESD-susceptibility testing and
protection design evaluation.
ESD voltage thresholds are dependent on the circuit
parameters used to define the mode. Although no industry-
wide standard has been adopted for the CDM, a standard HBM
(resistance = 1500
, capacitance = 100pF) is widely used and
therefore can be used for comparison purposes. The HBM
ESD threshold presented here was obtained by using these
circuit parameters.
