a given frequency. These generators are both keyable and synchronizable, producing a continuous output train as long as a TTL “low” is applied
to the input. With a TTL “high” applied to the input, output 1 will produce a constant “high” and output 2 will produce a constant “low”. When
the input switches to “low”, output 2 goes “high” immediately. Output 1 and output 2 both go low after one half-cycle and then run in phase as a
continuous square wave output. When the input switches back to “high”, output 2 goes “low” immediately and output 1 goes “high” one
half-cyclelater.
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 5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
