FX-400 low jitter frequency translator previous part number fx-424 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-400s 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. quartz-based pll for ultra-low jitter ? frequency translation up to 1 ghz ? accepts up to 4 ext.-muxed clock inputs ? lvcmos / lvds / lvpecl inputs compatible ? di" erential lvpecl /lvds or lvcmos output ? lock detect / loss of signal alarms ? output disable ? 20.3 x 13.7 x 5.1 mm smt package ? rohs/lead free compliant ? wireless infrastructure ? 10 gigabit fc ? 10gbe lan / wan ? oadm and ip routers ? test equipment ? military communications ? features applications block diagram description FX-400 phase detector & ld loop filter vcso ld (10) figure 1. functional block diagram fin (13) (8) fout 1 vcc (14) vmon (5) od (6) gnd (3, 7, 11, 12) $ controller fin (13 (9) cfout 1 sel0 (1) sel1 (2) fin 1 fin 2 fin 4 fin 3 vectron international ? 267 lowell road, hudson, nh 03051 ? tel: 1-88-vectron-1 ? http://www.vectron.com page 1 of 10 rev: 10jun2011

stresses in excess of the absolute maximum ratings can permanently damage the device. functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet. exposure to absolute maximum ratings for extended periods may adversely a ect device reliability. although esd protection circuitrry has been designed into the the FX-400, proper precautions should be taken when handling and mounting. vi employs a human body model and a charged-device model (cdm) for esd susceptibility testing and design protection evaluation. esd thresholds are dependent on the circuit parameters used to de! ne the model. although no industry wide standard has been adopted for the cdm, a standard hbm of resistance=1.5kohms and capacitance = 100pf is widely used and therefore can be used for comparison purposes the FX-400 is capable of meeting the following quali! cation tests vectron international ? 267 lowell road, hudson, nh 03051 ? tel: 1-88-vectron-1 ? http://www.vectron.com page 3 of 10 rev: 10jun2011 reliability absolute maximum ratings table 2. absolute maximum ratings parameter symbol ratings unit power supply v dd 6 v storage temperature t str -55 to 125 "c soldering temp/time t ls 260/40 "c/sec table 3. environmental compliance parameter conditions mechanical shock mil-std-883, method 2002 mechanical vibration mil-std-883, method 2007 solderability mil-std-883, method 2003 gross and fine leak mil-std-883, method 1014 resistance to solvents mil-std-883, method 2016 handling precautions table 4. predicted esd ratings model minimum conditions human body model 500 v mil-std 883, method 3015 charged device model 500 v jedec, jesd22-c101 FX-400 low jitter frequency translator
