Description
The J-type voltage controlled crystal oscillator
expands VI’s advanced VCXO performance
capabilities while adhering to a package footprint
compatible with the industry-common J-lead package.
The J-type VCXO is a quartz stabilized square wave
generator with either a CMOS output for driving
CMOS/TTL loads or a PECL output. The device is
packaged in a 6 pin J-lead ceramic package and is
hermetically sealed with a grounded conductive lid.

The first section of this data sheet covers the
performance/packaging/tape and reel/ordering
information for the CMOS version and then the
information for the PECL option follows.

2. Figure 1 defines these parameters. Figure 2 illustrates the load used to test devices.
3. Duty cycle is defined as on-time versus period at 1.4 V for TTL, and 2.5 V for CMOS (5volt supply) and at 1.65 V for CMOS (3.3

Handling Precautions
Although ESD protection circuitry has been designed into the the J-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.
