FX-702-SYNCE-156M250000 Complete VCSO Based Phase Lock Loop For Synchronous Ethernet Jitter Attenuation FX-702 Description The FX-702 is a low jitter precision frequency translator that provides clock smoothing/jitter attenuation of a 156.25 MHz input clock. 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.

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. Table 2.

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. Table 4.

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. 5 Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • http://www.vectron.com Rev: 22Sep2009 Application Circuits The FX-702 includes a phase detector, charge pump, frequency dividers and a VCSO with its own an associated divide-by function.
