IDTTM PCIe Gen2 and QPI Clock for Intel-Based Servers 1340G—01/26/10 18 ICS932S421B PCIe Gen2 and QPI Clock for Intel-Based Servers PD, Power Down PD is an asynchronous active high input used to shut off all clocks cleanly prior to system power down. When PD is asserted, all clocks will be driven low before turning off the VCO. All clocks will start without glitches when PD is de-asserted. PD 0 1 CPU Normal Iref * 2 or Float CPU # Normal Float SRC Normal Iref * 2 or Float SRC# Normal Float PCIF/PCI 33MHz Low USB 48MHz Low REF 14.318MHz Low Note 1 1 Notes: 1. Refer to SMBus Byte 4 for additional information. PD Assertion PD should be sampled high by 2 consecutive CPU# rising edges before stopping clocks. All single ended clocks will be held low on their next high to low transition. All differential clocks will be held high on the next high to low transition of the complimentary clock. If the control register determining to drive mode is set to 'tri-state', the differential pair will be stopped in tri-state mode, undriven. When the drive mode corresponding to the CPU or SRC clock of interest is set to '0' the true clock will be driven high at 2 x Iref and the complementary clock will be tristated. If the control register is programmed to '1' both clocks will be tristated. See SMBus Bytes 4 and 5 for additional information.
