Description
A crystal controlled, hybrid oscillator
circuit that produces a true TTL output
characteristic at frequencies between
4.0001 MHz 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.
