CLOCK DISTRIBUTION SYSTEM |
摘要 |
A clock distribution system includes a clock generation and distribution part for generating a clock signal and distributing the generated clock signal to a plurality of destinations, slots in each of which a clock reception unit can be detachably mounted, and a plurality of transmission lines coupling the clock generation and distribution part to the slots. Each slot includes a circuit for generating a mount state signal which indicates whether or not the slot is mounted with a clock reception unit, and for supplying the mount state signal to the clock generation and distribution part via a transmission line. This mount state signal has a first state when no clock receiving unit is mounted in the slot and has a second state when a clock receiving unit is mounted in the slot. The clock generation and distribution part includes a circuit for receiving the mount state signal from each slot and for transmitting via the transmission line the clock signal to each slot from which a mount state signal having the second state is received.
