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.
