Intel E5-1428L CM8062001144000 Data Sheet

The Direct Media Interface Gen 2 (DMI2) sends and receives packets and/or

commands to the PCH. The DMI2 is an extension of the standard PCI Express

Specification. The DMI2/PCI Express Signals consist of DMI2 receive and transmit

input/output signals and a control signal to select DMI2 or PCIe* 2.0 operation for

on page 23 for further details.

The processor provides two Intel QPI ports for high speed serial transfer between

other processors. Each port consists of two uni-directional links (for transmit and

receive). A differential signaling scheme is utilized, which consists of opposite-polarity

(DP, DN) signal pairs.

PECI is an Intel proprietary interface that provides a communication channel between

Intel processors and chipset components to external system management logic and

thermal monitoring devices. The processor contains a Digital Thermal Sensor (DTS)

that reports a relative die temperature as an offset from Thermal Control Circuit (TCC)

activation temperature. Temperature sensors located throughout the die are

implemented as analog-to-digital converters calibrated at the factory. PECI provides

an interface for external devices to read processor temperature, perform processor

manageability functions, and manage processor interface tuning and diagnostics.

The PECI interface operates at a nominal voltage set by V

CCPECI

. The set of DC

electrical specifications shown in 

 on page 38 is used with

devices normally operating from a V

CCPECI

 interface supply.

The PECI client and host input buffers must use a Schmitt-triggered input design for

improved noise immunity. Please refer to the following image and 

 on page 38.
