Applications
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 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.
• Wireless Infrastructure
• 802.16 BTS
• 10 Gigabit FC
• 10GbE LAN / WAN
• OADM and IP Routers
• Test Equipment

Parameters are tested with production test circuit below (Fig 2).
Parameters are tested at ambient temperature with test limits guard banded for specified operating temperature.
Measured from 20% to 80% of a full output swing (Fig 3).
Not tested in production, guaranteed by design, verified at qualification.
The FX-427 phase noise and jitter performance can be optimized for specific applications. Please consult with Vectron’s Application
Engineers for more information.

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

Mechanical Shock
Mechanical Vibration
Solderability
Gross and Fine Leak

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

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.

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.
