Signal Groups

The signal description includes the type of buffer used for the particular signal:

GTL+

Open Drain GTL+ interface signal. Refer to the GTL+ I/O Specification

for complete details. The (G)MCH integrates most GTL+ termination

resistors.

DDR

DDR System memory (2.6 V CMOS buffers)

DDR2

DDR2 System memory (1.8 V CMOS buffers)

PCI Express/SDVO

PCI Express interface signals. These signals are compatible with PCI

Express 1.0a signaling environment AC Specifications. The buffers are

not 3.3 V tolerant.

Analog

Analog signal interface

Ref

Voltage reference signal

HVCMOS

2.5 V Tolerant High Voltage CMOS buffers

SSTL-2

2.6 V Tolerant Stub Series Termination Logic

SSTL-1.8

1.8 V Tolerant Stub Series Termination Logic
