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.
