ABSTRACT:
A circuit and method for providing phase synchronization between an ECL output signal and a TTL or CMOS output signal has been provided. The circuit includes phase locked loops (20, 24) to make the difference of delays through an ECL-TTL/CMOS translation path with that of a straight ECL path irrelevant. As a result, in order to achieve phase synchronization between an ECL signal and a TTL/CMOS signal, one only needs to match the propagation delay of a delay component (22) to that of a TTL/CMOS-ECL translator (26) as opposed to a delay component and an ECL-TTL/CMOS translator.
