FASTTTLDigitalFrequencyMultiplierModule
The FAST TTL Digital Frequency Multiplier Modules manufactured by Engineered Components Company are designed to provide a square
waveoutputatagivenfrequencywhichcanbesynchronizedbysquarewaveinputsatsub-harmonicfrequencies.Thefallingedgeof the
output waveform is synchronized to the falling edge of the input waveform. If no synchronizing input is present, the unit will free-run,
producingacontinuousoutputsquarewave.Phasejitterattheoutputwillincreaseashigherordersof multiplicationareused.
TheMTBFonthesemodules,whencalculatedperMIL-HDBK-217,fora50deg.Cgroundfixedenvironmentandwith50VDCapplied,isin
excess of 3 million hours. The temperature coefficient of delay is less than 500 ppm/deg.C over the operating temperature range of 0
to+70deg.C.
Themoduleisprovidedina14-pinDIPpackage,fullyencapsulatedinepoxyresinandishousedinaDiallylPhthalatecase,blueincolor.
The case marking is applied by silkscreen using white epoxy paint. The 4 copper leads are tin-lead plated and meet the solderability
requirementsof MIL-STD-202,Method208.
