FX-702
Low Jitter VCSO Frequency Translator
Previous Part Number FX-730
FX-702
Description
The FX-702 is a low jitter precision frequency translator used to translate input frequencies such as 19.44, 38.88, 77.76 MHz, etc. to
a binary multiple frequency as high as 850 MHz. The FX-702’s superior jitter performance is achieved through the PLL’s integrated
VCSO. The FX-702 is housed in a hermetically sealed leadless surface mount package offered on tape and reel.
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 circuitry has been designed into the the FX-702, 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. ESD thresholds are dependent on the circuit parameters used to define the model.

The device has been 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-702 device is
hermetically sealed so an aqueous wash is not an
issue.

It is recommended that a buffer driver is used for best noise isolation.
Do not leave the MODE pin floating, it should be set to logic 0 or ground for normal operation.
BRCLK and CBRCLK should be left floating if not used.
FIN, CFIN, BRCLK, and CBRCLK have internal pull-up/pull-down resistors and it is recommended to AC couple these inputs.
