FX-427
Low Jitter Frequency Translator
FX-427
Description
The FX-427 is a precision quartz-based frequency translator used to translate 1 to 4 selected input clocks as low as 8 kHz to an
integer multiple as high as 850 MHz. The FX-427âs superior jitter performance is achieved through the filtering action of the on-
board voltage-controlled SAW oscillator (VCSO) and integrated loop filter. Two low-jitter outputs are provided. Monitoring and
control functionality are also standard features.
