Description
The J-type voltage controlled crystal oscillator incorpo-
rates 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 pack-
aged in a 6 pin J-lead ceramic package and is hermeti-
cally sealed with a grounded conductive lid.

Recommended Solder Reflow Profile
Suggested IR profile
a preheat period in which the flux is activated, a ramp
VI qualification includes aging at various extreme tem-
peratures, shock and vibration; temperature cycling
and IR reflow simulation. The conditions a device can
withstand are well understood and devices can be
subjected to the profile in figure above. This profile
shows a ramp up condition to prevent thermal shock,
up to 183° C which is the eutectic temperature of Sn/Pb
and a gradual cool down. The time above 183° C should
not exceed 60 seconds and the peak temperature
should be no more than 220° C for 10 seconds. The J-
types are 100% screened for hermeticity so an aqueous
wash is not an issue.

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 pro-
tection 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.
