Abstract
A device for transmitting clock signals to a microprocessor is disclosed. The device is configured to receive a clock signal and distribute the signal synchronically to multiple output sites on the device. The synchronized clock signals are transmitted from the various device sites to multiple sites on the microprocessor.
Claims8
A clock signal distribution device formed on a semiconductor substrate, comprising:
- a clock input;
- a first driver coupled to said clock input;
- a second driver coupled to said clock input;
- a first receiver coupled to said first driver by a first plurality of transmission lines;
- a second receiver coupled to said second driver by a second plurality of transmission lines;
- said first and second plurality of transmission lines being configured to provide substantially equal time delays;
- said first receiver configured to provide a first output connected to a first site on a microprocessor;
- and
- said second receiver configured to provide a second output connected to a second site on said microprocessor.
