FX-703
Low Jitter VCSO Frequency Translator
Jitter Attenuator
FX-703
Description
The FX-703 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 1 GHz. The FX-703’s superior jitter performance is achieved through the PLL’s integrated
VCSO. The FX-703 is housed in a hermetically sealed leadless surface mount package offered on tape and reel.
