Title:
RELAY FOR TRIPLE CLOCK DISTRIBUTION
Document Type and Number:
Japanese Patent JPS61184941
Kind Code:
A
Abstract:
In a triplicated clock distribution system each clock delivers a clock and synchronization signal that comprises a clock signal and a synchronization signal, the latter consisting of a negative and a positive pulse each having a duration equal to the period of the clock signal. Each clock is connected to a receiver by at least one repeater. A repeater comprises an inverter, an inverter circuit, a test circuit, a restore and shift circuit and a regenerator circuit. The test circuit tests the duration of the pulses in order to detect the synchronization signal and delivers a pulse in response to such detection of the synchronization signal. The restore circuit delivers a pulse the duration of which is equal to one pulse of the synchronization signal, shifted by two periods of the clock signal. The inverter circuit inverts the edge between the two pulses of the synchronization signal and the clock generator circuit delivers a clock and synchronization signal to the output of the repeater.
