ABSTRACT:
A clock signal is distributed over a circuit board and across a connector as a sine wave. A circuit located near the clocked circuitry converts the sine wave into a same frequency square wave for use by the clocked circuitry. The output stage of the converter circuitry provides a high output level to drive CMOS circuitry. The output transistor is pulled up to 5 volts, but the preceding transistors are pulled up to 6.3 volts so that the base to emitter drops are compensated.
