Crystal Clock

This document provides the specifications for the Type R405 Crystal Clock. The module incorporates a series resonant crystal oscillator, a squaring circuit, and an output pulse amplifier. It is designed to maintain a frequency stability within 0.01% between 0°C and +55°C. The clock frequency can be specified by the customer within the 5 kc to 2 mc range. Key technical details include an output of a 100-nsec pulse (-3v to ground) capable of driving a 70 ma external load, and power requirements of -10v at 5.4 ma and -15v at 50 ma.
