FX-400
Low Jitter Frequency Translator
Previous Part Number FX-424
FX-400
Description
The FX-400 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 speci c frequency from 1.544 MHz to 1.0 GHz. The FX-400 can perform either up or down frequency
conversion. The FX-400’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 di erent input clocks can be translated to a common output frequency.
