VECTRON FX-427

FX-427
Low Jitter Frequency Translator
FX-427
Description
The FX-427 is a precision quartz-based frequency translator used to translate 1 to 4 selected input clocks as low as 8 kHz to an
integer multiple as high as 850 MHz. The FX-427’s superior jitter performance is achieved through the filtering action of the onboard voltage-controlled SAW oscillator (VCSO) and integrated loop filter. Two low-jitter outputs are provided. Monitoring and
control functionality are also standard features.

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 circuitrry has been designed into the the FX-427, 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

The FX-427 is qualified to meet the JEDEC
standard for Pb-Free assembly. The temperatures
and time intervals listed are based on the Pb-Free
small body requirements. The temperatures refer
to the topside of the package, measured on the
package body surface. The FX-427 should not
be subjected to a wash process that will immerse
it in solvents. NO CLEAN is the recommended
procedure. The FX-427 has been designed for pick
and place reflow soldering. The FX-427 may be
reflowed once and should not be reflowed in the
inverted position.

LV-PECL to LV-PECL: For short transmission lengths, the power
consumption could be reduced by removing the 100Ω resistor and
doubling the value of the pull down resistors.
