Interfaces

28 Datasheet, Volume 1 of 2

• Full RX Equalization and acquisition for: AGC (Adaptive Gain Control), CDR (Clock

and Data Recovery), adaptive DFE (decision feedback equalizer) and adaptive CTLE

peaking (continuous time linear equalizer).

• Full adaptive phase 3 EQ compliant with PCI Express* Gen 3 specification

See the PCI Express* Base Specification 3.0 for details on PCI Express* equalization.

2.3 Direct Media Interface (DMI)

Direct Media Interface (DMI) connects the processor and the PCH.

Main characteristics:

• 4 lanes Gen 3 DMI support

• 8 GT/s point-to-point DMI interface to PCH

• DC coupling - no capacitors between the processor and the PCH

• PCH end-to-end lane reversal across the link

• Half-Swing support (low-power/low-voltage)

Note: Only DMI x4 configuration is supported.

2.3.1 DMI Lane Reversal and Polarity Inversion

Note: Polarity Inversion and Lane Reversal on DMI Link are not allowed in S-Processor Line

paired with Intel

Z370 Series Chipset PCH-H.
