The following sections provide detail information about the functions provided onboard.

16 AIMB-250 Series User’s Manual

User’s Manual

1.6.2 Intel 855GME and ICH4

The Intel 855GME GMCH components provide the processor interface, DDR SDRAM

interface, display interface, and Hub interface. The Intel 855GME also has an option for

AGP external graphics port, in addition to integrated graphics support for added board

flexibility options.

The Intel 855GM GMCH is in a 732-pin Micro-FCBGA package and contains the following

functionality listed below:

• AGTL+ host bus supporting 32-bit host addressing with Enhanced Intel SpeedStep

technology support

• Supports a single channel of DDR SDRAM memory

• System memory supports DDR200/266 MHz (SSTL_2) DDR SDRAM

• Integrated graphics capabilities: Display Core frequency at 133 MHz or 200 MHz

• Render Core frequency at 100 MHz ,133 MHz, and 200 MHz

• Provides supports four display ports: one progressive scan analog monitor, dual

channel LVDS interface and two DVO port.

The Intel EE GMCH is in a 732-pin Micro-FCBGA package and contains all features listed

above and the additional functionality list below:

• Display Core frequency at 133 MHz, 200 MHz, or 250 MHz

• Render Core frequency at 100 MHz ,133 MHz, 166 MHz, 200 MHz, or 250 MHz

• System memory supports 200/266/333- MHz (SSTL_2) DDR SDRAM.

• Enhanced Power Management Graphics features

The GMCH IGD provides a highly integrated graphics accelerator delivering high

performance 2D, 3D, and video capabilities. With its interfaces to UMA using a DVMT

configuration, an analog display, a LVDS port, and two digital display ports (e.g. flat panel),

the GMCH can provide a complete graphics solution.

The GMCH also provides 2D hardware acceleration for block transfers of data (BLTs). The

BLT engine provides the ability to copy a source block of data to a destination and perform

raster operations (e.g., ROP1, ROP2, and ROP3) on the data using a pattern, and/or

another destination. Performing these common tasks in hardware reduces CPU load, and

thus improves performance. High bandwidth access to data is provided through the system

memory interface. The GMCH uses Tiling architecture to increase system memory

efficiency and thus maximize effective rendering bandwidth. The Intel 855GME GMCH

improves 3D performance and quality with 3D Zone rendering technology. The Intel

855GME GMCH also supports Video Mixer rendering and Bi-Cubic filtering.

AIMB-250 User’s Manual

AIMB-250 Series

The Intel 855GME GMCH has four display ports, one analog and three digital. With these

interfaces, the GMCH can provide support for a progressive scan analog monitor, a

dedicated dual channel LVDS LCD panel, and two DVO devices. Each port can transmit

data according to one or more protocols. The data that is sent out the display port is

selected from one of the two possible sources, Pipe A or Pipe B.

The Intel 855GME GMCH have an integrated dual channel LFP Transmitter interface to

support LVDS LCD panel resolutions up to UXGA The display pipe provides panel

up-scaling to fit a smaller source image onto a specific native panel size, as well as

provides panning and centering support. The LVDS port is only supported on Pipe B. The

LVDS port can only be driven by Pipe B, either independently or simultaneously with the

Analog Display port. Spread Spectrum Clocking is supported: center and down spread

support of 0.5%, 1%, and 2.5% utilizing an external SSC clock.

The DVO B/C interface is compliant with the DVI Specification 1.0. When combined with a

DVI compliant external device (e.g. TMDS Flat Panel Transmitter, TV-out encoder, etc.),

the GMCH provides a high-speed interface to a digital or analog display (e.g. flat panel, TV

monitor, etc.). The DVO ports are connected to an external display device. Examples of this

are TV-out encoders, external DACs, LVDS transmitters, and TMDS transmitters. Each

display port has control signals that may be used to control, configure and/or determine the

capabilities of an external device. The GMCH provides two DVO ports that are each

capable of driving a 165-MHz pixel clock at the DVO B or DVO C interface. When DVO B

and DVO C are combined into a single DVO port, then an effective pixel rate of 330 MHz

can be achieved. The DVO B/C ports can be driven by Pipe A or Pipe

B. If driven on Pipe B, then the LVDS port must be disabled.

The ICH4 is a highly integrated multifunctional I/O Controller Hub that provides the

interface to the PCI Bus and integrates many of functions needed in today’s PC platform.

The GMCH and ICH4 communicate over a dedicated hub interface. The ICH4 functions

and capabilities include:

• PCI Rev. 2.2 compliant with support for 33MHz PCI operations

• Supports up to 6 Request/Grant pairs (PCI slots)

• Power management logic support

• Enhanced DMA controller, interrupt controller, and timer functions

• Integrated IDE controller; Ultra ATA/100/66/33

• USB host interface; 3 host controllers and supports 6 USB ports; includes a EHCI

high-speed 2.0 USB controller

1.6.10 Chrontel CH7009A TV/DVI Transmitter

The Chrontel CH7009A is a display controller device which accepts a digital graphics input

signal, and encodes and transmits data through a DVI (DFP can also be supported) or TV

output (analog composite, s-video or RGB). The device accepts data over one 12-bit wide

variable voltage data port which supports five different data formats including RGB and

YCrCb.

The DVI processor includes a low jitter PLL for generation of the high frequency serialized

clock, and all circuitries are required to encode, serialize and transmit data. The CH7009

comes in versions able to drive a DVI display at a pixel rate of up to 165MHz, supporting

UXGA resolution displays. No scaling of input data is performed on the data output to the

DVI device.

The TV-Out processor performs non-interlace to interlace conversion with scaling and

flicker filters, and encode the data into any of the NTSC or PAL video standards. The

scaling and flicker filter is adaptive and programmable to enable superior text display.

Eight graphics resolutions are supported up to 1024 by 768 with full vertical and horizontal

underscan capability in all modes. A high accuracy low jitter phase locked loop is

integrated to create outstanding video quality. Support is provided for MacrovisionTM and

1.6.11 Ethernet

1.6.11.1 Realtek RTL8110S Gigabit Ethernet Controller

The Realtek RTL8110SB(L) LOM Gigabit Ethernet controllers (RTL8110SB (128 QFP) &

RTL8110SBL (128 LQFP)) combine a triple-speed IEEE 802.3 compliant Media Access

Controller (MAC) with a triple-speed Ethernet transceiver, 32-bit PCI bus controller, and

embedded memory. With state-of-the-art DSP technology and mixed-mode signal

technology, they offer high-speed transmission over CAT 5 UTP cable or CAT 3 UTP

(10Mbps only) cable. Functions such as Crossover Detection & Auto-Correction, polarity

correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery,

and error correction are implemented to provide robust transmission and reception

capability at high speeds.

The devices support the PCI v2.3 bus interface for host communications with power

management and are compliant with the IEEE 802.3 specification for 10/100Mbps Ethernet

and the IEEE 802.3ab specification for 1000Mbps Ethernet. They also support an auxiliary

power auto-detect function, and will auto-configure related bits of the PCI power

management registers in PCI configuration space.

They support the Advanced Configuration Power management Interface (ACPI)--power

management for modern operating systems that are capable of Operating System-directed

Power Management (OSPM)--to achieve the most efficient power management possible.

PCI Message Signaled Interrupt (MSI) is also supported.

In addition to the ACPI feature, the RTL8110SB(L) support remote wake-up (including AMD

Magic Packet, Re-LinkOk, and Microsoft® Wake-up frame) in both ACPI and APM

(Advanced Power Management) environments. The LWAKE pin provides four different

output signals including active high, active low, positive pulse, and negative pulse. The

versatility of the LWAKE pin provides motherboards with Wake-On-LAN (WOL)

functionality. To support WOL from a deep power down state (e.g. D3cold, i.e. main power

is off and only auxiliary exists), the auxiliary power source must be able to provide the

needed power for the RTL8110SB(L).

The RTL8110SB(L) is fully compliant with Microsoft® NDIS5 (IP, TCP, UDP) Checksum

and Segmentation Task-offload features, and supports IEEE 802 IP Layer 2 priority

encoding and 802.1Q Virtual bridged Local Area Network (VLAN). The above features

contribute to lowering CPU utilization, especially benefiting performance when in operation

on a network server. Also, the devices boost their PCI performance by supporting PCI

Memory Read Line & Memory Read Multiple when transmitting, and Memory Write and

Invalidate when receiving. To better qualify for server use, the RTL8110SB(L) support the

PCI Dual Address Cycle (DAC) command when the assigned buffers reside at a physical

memory address higher than 4 Gigabytes.
