13.0 DC Characteristics
13.1 Signal Groups
The signal description includes the type of buffer used for the particular signal. Please
refer to the Chapter 2.0 for signals detail.
Table 402. Memory Controller Buffer Types
Buffer Type Description
AGTL+
Assisted Gunning Transceiver Logic Plus. Open Drain interface signals that require
termination. Refer to the AGTL+ I/O Specification for complete details.
CMOS,
CMOS Open Drain
1.05-V CMOS buffer
CMOS_HDA CMOS buffers for Intel

interface, 3.3-V operation.
CMOS1.8
1.8-V CMOS buffer. These buffers can be configured as Stub Series Termination
Logic (SSTL1.8)
CMOS3.3,
CMOS3.3 Open Drain
3.3-V CMOS buffer
CMOS3.3-5 3.3-V CMOS buffer, 5-V tolerant
PCIe*
PCI Express* interface signals. These signals are compatible with PCI Express*
Base Specification, Rev. 1.0a Signaling Environment AC Specifications and are AC
coupled. The buffers are not 3.3-V tolerant. Differential voltage specification =
(|D+ - D-|) x 2 = 1.2 V
max
. Single-ended maximum = 1.5 V. Single-ended
minimum = 0 V.
SDVO Serial-DVO differential output buffers. These signals are AC coupled.
LVDS
Low Voltage Differential Signal buffers. These signals should drive across a 100-
Ohm resistor at the receiver when driving.
Analog
Analog reference or output. Can be used as a threshold voltage or for buffer
compensation.
