Description
A crystal controlled, hybrid oscillator
circuit that produces a true TTL output
characteristic at frequencies between 500
kHz and 66.6667 MHz. The device is
mounted in a 14-pin DIP-compatible, all
metal hermetic package. Physically and
functionally interchangeable with all
major manufacturers' devices.
