Abstract
A circuit for producing a receive Manchester clock from serially received Manchester encoded data signals. The encoded data signals are differentiated to produce a primary clock pulse for each voltage transition of the applied signals. Each primary clock pulse is delayed a predetermined period of time to produce secondary clock pulse and each secondary clock pulse is delayed for substantially the same period of time to produce a tertiary clock pulse. The primary, secondary and tertiary clock pulses are applied to a gate which produces a receive Manchester clock pulse when a primary, secondary, or tertiary clock pulse is applied to the gate. The frequency of the receive Manchester clock is twice that of the basic frequency of the received Manchester encoded data signals.
