FAST TTL Digital Frequency Multiplier Module
The FAST TTL Digital Frequency Multiplier Modules manufactured by Engineered Components Company are designed to provide a square
wave output at a given frequency which can be synchronized by square wave inputs at sub-harmonic frequencies. The falling edge of the
output waveform is synchronized to the falling edge of the input waveform. If no synchronizing input is present, the unit will free-run,
producing a continuous output square wave. Phase jitter at the output will increase as higher orders of multiplication are used.
The MTBF on these modules, when calculated per MIL-HDBK-217, for a 50 deg.C ground fixed environment and with 50VDC applied, is in
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 +70 deg. C.
The module is provided in a 14-pin DIP package, fully encapsulated in epoxy resin and is housed in a Diallyl Phthalate case, blue in color.
The case marking is applied by silkscreen using white epoxy paint. The 4 copper leads are tin-lead plated and meet the solderability
requirements of MIL-STD-202, Method 208.
