82845G/82845GL/82845GV GMCH Datasheet
2.4.6
PCI Pins during PCI Transactions on AGP Interface
The PCI signals described in
Section 2.4.5
behave according to
PCI Local Bus Specification,
Revision 2.1
, when used to perform PCI transactions on the AGP Interface.
2.5
Multiplexed Intel
DVO Device Signal Interfaces
The DVO signals, described in the following table, are multiplexed with the AGP signals.
Name
Type
Description
DVOB_CLK;
DVOB_CLK#
O
AGP
DVOB Clock Output:
These signals provide a differential pair reference
clock that can run up to 165 MHz. Formerly known by:
DVOB_CLKOUT0=DVOB_CLK and DVOB_CLKOUT1=DVOB_CLK#. Care
should be taken to be sure that DVOB_CLK is connected to the primary clock
receiver of the Intel
DVO device.
DVOB_D[11:0]
O
AGP
DVOB Data:
This data bus is used to drive 12-bit pixel data on each edge of
DVOB_CLK(#). This provides 24 bits of data per clock.
DVOB_HSYNC
O
AGP
Horizontal Sync:
This is the HSYNC signal for the DVOB interface. The
active polarity of the signal is programmable.
DVOB_VSYNC
O
AGP
Vertical Sync:
This is the VSYNC signal for the DVOB interface. The active
polarity of the signal is programmable.
DVOB_BLANK#
O
AGP
Flicker Blank or Border Period Indication:
DVOB_BLANK# is a
programmable output pin driven by the GMCH. When programmed as a
blank period indication, this pin indicates active pixels excluding the border.
When programmed as a border period indication, this pin indicates active
pixel including the border pixels.
DVOBC_CLKINT#
I
AGP
DVOBC Pixel Clock Input/Interrupt:
This signal may be selected as the
reference input to the dot clock PLL (DPLL) for the multiplexed DVO devices.
This pin may also be programmed to be an interrupt input for either of the
multiplexed DVO devices.
DVOB_FLDSTL
I
AGP
TV Field and Flat Panel Stall Signal:
This input can be programmed to be
either a TV Field input from the TV encoder or Stall input from the flat panel.
When used as a Field input, it synchronizes the overlay field with the TV
encoder field when the overlay is displaying an interleaved source. When
used as the Stall input, it indicates that the pixel pipeline should stall one
horizontal line. The polarity is programmable for both modes and the input
may be disabled completely.
DVOC_CLK;
DVOC_CLK#
O
AGP
DVOC Clock Output:
These pins provide a differential pair reference clock
that can run up to 165 MHz. Formerly known by:
DVOC_CLKOUT0=DVOC_CLK and DVOC_CLKOUT1=DVOC_CLK#. Care
should be taken to be sure that DVOC_CLK is connected to the primary
clock receiver of the DVO device.
DVOC_D[11:0]
O
AGP
DVOC Data:
This data bus is used to drive 12-bit pixel data on each edge of
DVOC_CLK(#). This provides 24 bits of data per clock.
DVOC_HSYNC
O
AGP
Horizontal Sync:
This is the HSYNC signal for the DVOC interface. The
active polarity of the signal is programmable.
DVOC_VSYNC
O
AGP
Vertical Sync:
This is the VSYNC signal for the DVOC interface. The active
polarity of the signal is programmable.
DVOC_BLANK#
O
AGP
Flicker Blank or Border Period Indication:
DVOC_BLANK# is a
programmable output pin driven by the GMCH. When programmed as a
blank period indication, this signal indicates active pixels excluding the
border. When programmed as a border period indication, this signal indicates
active pixel including the border pixels.
