ABSTRACT:
A digital spread spectrum clock circuit is made variable by employing RAM memory (29), and a multiplexer (39) to receive initiation data before the circuit is ready to run normally. A second counter (17) and an adder (25) each receiving the contents of programmable registers (17 and 25) permit wide variation in operation although RAM memory is of relatively small size.
