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 on-board voltage-controlled SAW oscillator
(VCSO) and integrated loop filter. Two low-jitter
outputs are provided. Monitoring and control
functionality are also standard features.

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.
Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR
reflow simulation. The FX-427 family is undergoing the following qualification tests:
Environmental Compliance

Handling Precautions
Although ESD protection circuitry has been designed into the FX-427 proper precautions should be taken when
handling and mounting. VI employs a human body model (HBM) and a charged-device model (CDM) for ESD
susceptibility testing and design protection evaluation

Vectron plans to offer both tape-n-reel and matrix trays as packaging options for the FX-427. The standard
shipping container for volume production is a matrix tray. The trays are 100% recyclable and offer the added
feature that they can be continuously fed into a pick-n-place machine.
