Clock Generation and Distribution

4. Clock Generation and Distribution
All buses on the Intel Server Boards SE7320EP2 / SE7525RP2 operate using synchronous
clocks. Clock synthesizer/driver circuitry on the server board generates clock frequencies and
voltage levels as required, including the following:
200 MHz at 0.7V current-mode: For processor 0, processor 1, debug port and MCH
66 MHz at 3.3 V logic levels: For MCH, 6300ESB ICH
48 MHz at 3.3V logic levels: For 6300ESB ICH
33 MHz at 3.3V logic levels: For 6300ESB ICH, PCI connector, Super I/O
14.318 MHz at 2.5 V logic levels: For 6300ESB ICH , Super I/O and video
The following figure illustrates clock generation and distribution on the board.
