FX-424
Low Jitter Frequency Translator
FX-424
Description
The FX-424 is a precision quartz-based frequency translator used to translate an input frequency such as 8 kHz, 1.544 MHz, 2.048
MHz, 19.44 MHz etc. to any specific frequency from 1.544 MHz to 1.0 GHz. The FX-424 can perform either up or down frequency
conversion. The FX-424’s superior jitter performance is achieved through the use of a precision VCXO or VCSO. With the use of an
external multiplexer, up to 4 different input clocks can be translated to a common output frequency.
