Description
Applications
The FX-424 is a precision quartz-based frequency
translator used to translate an input frequency such
as 8 kHz, 1.544 MHz, 2.048 MHz, 19.44 MHz etc.
to any specific frequency from 1.544 MHz to 850
MHz. The FX-424 can perform either up or down
frequency conversion. The FX-424’s superior jitter
performance is achieved through the use of a
precision VCXO or VCSO. With the use of an
external multiplexer, up to 4 different input clocks
can be translated to a common output frequency.

Handling Precautions
Although ESD protection circuitry has been designed into the FX-424 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-424 is being 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-424 should not be subjected to
a wash process that will immerse it in solvents. NO
.CLEAN is the recommended procedure. The FX-424
has been designed for pick and place reflow
soldering. The FX-424 may be reflowed once and
should not be reflowed in the inverted position.
