Interpret The HDMI architecture consists of at least one HDMI source and sink. HDMI is composed of four TMDS channels responsible for sending
out information from the HDMI transmitter to the HDMI receiver. The three TMDS data channels are responsible for transmitting the video, audio, and auxiliary data and the TMDS clock channel is responsible for transmitting the video pixel clock data, used for data recovery on the three TMDS data channels.
The DDC channel provides the communication gateway to exchange the status and E-EDID information between the HDMI source and the HDMI sink.
The optional CEC channel provides the high-level control functionality, used for infrared remote control usage.
Limitations include: The optional CEC channel is unsupported
ASUS Confidential 150
Integrated and SDVO HDMI
The digital display port on the GMCH supports two HDMI options: Integrated and SDVO HDMI.
Integrated HDMI uses the integrated HDMI transmitter on the digital display port
SDVO HDMI uses the integrated SDVO transmitter on the digital display port, and then uses the third party HDMI transmitter on either the motherboard or ADD2 card
ASUS Confidential 151
Integrated HDMI Option For Integrated HDMI, the integrated HDMI transmitter receives both the
digital video and audio data which it synchronizes before it transmits the data across a single cable connection to the HDMI receiver on the HDMI sink.
ASUS Confidential 152
SDVO HDMI Option For SDVO HDMI, the integrated SDVO transmitter receives the digital
video data and transmits the data to a third party HDMI transmitter on either the motherboard or an ADD2 card. The third party HDMI transmitter receives both the digital video and audio data which it synchronizes before it transmits the data across a single cable connection to the HDMI receiver on the HDMI sink.

What is MAC Address? Each device connected to a standard LAN needs a Data Link Layer
address (or called hardware address), providing a means of unique identification.
Each NIC has its unique, hard-coded MAC (Media Access Control) address. It is a 48 bits (6 bytes) address written in a hexadecimal format. The first 3 bytes represents for vendor ID and the remaining 3 bytes are serial number.

LVDS Basic-1
LVDS is short for "Low Voltage Differential Signaling" and is a high speed, low power data transmission standard.
LVDS is standardized in the ANSI/TIA/EIA-644-1995 Electrical characteristics standard titled: "Electrical Characteristics of Low Voltage Differential Signaling (LVDS) Interface Circuits“
The LVDS standard is an electrical standard only defining driver output characteristics and receiver input characteristics. Guideline are also given on bus configuration, cables, and termination. Protocol, connectors, and bus structure is not defined in this standard, as they are application dependant. It is intended that these parameters are specified by the referencing standard.
ASUS Confidential 321
LVDS Basic-2
LVDS is envisioned to be forward looking and does not define a maximum data rate within the standard. As maximum data rate is design, technology, and application dependant (required signal quality). Current LVDS parts operate from DC to Giga bits per second range.
Power dissipation is minimized in a number of ways. This includes the CMOS process, the current mode driver design, and also the small load current.
Noise generation is minimized in a number of ways. The signal swing is only 300mV, and also a true balanced differential data transmission scheme, and the current mode driver all limit noise generation.

Introduction What is memory anyway? All computer functions have common features
Data processing (CPU, GPU….) Data storage (CDR, HDD, Memory…) Data movement (FSB, PCI-E, USB….) Control (North Bridge, South Bridge…)
Why memory improve performance? CPU runs much more faster than HDD.
If all data & application were stored in HDD.CPU will always wait for HDD to pass data.
Bottle neck in HDD, CPU idle most of the time Memory enhance the usage of CPU.

DDR Basic
Short for Double Data Rate-Synchronous DRAM,a type of SDRAM that supports data transfers on both edges of each clock cycle (the rising and falling edges), effectively doubling the memory chip's data throughput.
DDR-SDRAM also consumes less power, which makes it well-suited to notebook computers. DDR-SDRAM is also called SDRAM II and DDRAM.

DDR Electrical Interface Double Data Rate IC's use 2.5 volt SSTL_2
compatible I/O [class II], how ever the supply voltage may be higher. The main supply voltage [VDD] is 3.3v or 2.5v for DDR 200, DDR266, and DDR333, while 2.6v for DDR400. The output drive supply [VDDQ] is 3.3v or 2.5v for DDR200, DDR266, and DDR333, while it's 2.6v for DDR400. DDR uses a bi-directional data strobe to indicate valid data [DQS].
STL-2: Stub Series Terminated Logic for 2.5v [JESD8-9]. Class II provides for higher power dissipation, Higher drive and a maximum current of 15.2mA. DDR, Double Data Rate. [JESD79] defines two data transfers per clock cycle. The Clocks are differential. Power Supply [VDD = 3.3v + 0.3v or 2.5v + 0.02v for DDR 200, DDR 266, or DRR 333; and 2.6v +0.1v for DDR 400]. Inputs and outputs are compatible with SSTL_2. These DIMMs are 184 Pin in size and are not interchangeable with older 168 on SDRAM modules.

DDR2 Basic
DDR2 SDRAM (Double Data Rate Two Synchronous Dynamic Random Access Memory)
The advantage of DDR2 over DDR SDRAM is its ability to run at much higher clock speeds due to an improved electrical interface.
Like DDR, DDR2 will transfer data on every rising and falling edge of the clock (double pumped), achieving an effective rate of 200 MHz with the same clock frequency
ASUS Confidential 391
DDR2 Basic count. DDR2 DIMM memory modules are not backward-
compatible with DDR DIMM , due to incompatible pin configurations, core voltage, and memory chip technology.
DDR2 modules are designed with a different "key" in the edge connector to prevent insertion into incompatible memory sockets such as DDR motherboard. A DDR2 SDRAM DIMM will not fit into a standard SDRAM DIMM socket or a DDR DIMM socket.
DDR2 modules use a 1.8V power supply, providing a big power saving over the 2.5V DDR modules.
ASUS Confidential 392
DDR I /DDR II
In this scenario, the core is running at 100 MHz, for DDR I, the I/O buffers is synchronous with the core.
Only the protocol varies and in the case of DDR II, the I/O buffers are clocked at twice the core frequency. In order to satisfy the output
DDR I prefetches 2 bits, DDR II needs to prefetch four bits with every read command and pipeline them for time multiplexed output.

ASUS Confidential 397
DDR2 Termination DDR2 modules contain the require resistor termination located on the
memory chips using a technique called On-Die Termination [ODT]. While DDR1 modules have the necessary resistive termination located on the motherboard. Using ODT, DDR2 are able to reduce the parts count required for mother board while at the same time locate the terminations closer the the signal destination. The ODT termination can be turned on or off by the DRAM controller. Normally the terminations are turned on for Writes and disable for Reads. The value of the ODT termination is selectable based on the number of modules in the system. With one DIMM module the ODT value is set at 150 ohms [300Ω pull-up and 300Ω pull-down]. When two modules are loaded into the system the ODT value is changed to 75 ohms [150Ωpull-up and 150Ω pull-down] for the DIMM not being written to while the DIMM being accessed has its ODT turned off. Writing to the Extended Mode Register [EMR] controls the ODT presence and value. Three combinations are allowed; termination disabled, 75 ohms, and 150 ohms [ also 50 ohms]. The newest revision adds 50 ohm termination values. ODT improves the eye-diagram over SSTL for either Single-Rank or Dual-Rank modules.

DDR 3 DDR3 SDRAM(Double Data Rate Three Synchronous
Dynamic Random Access Memory) DDR3 SDRAM improves on DDR2 SDRAM in several
significant ways:1.Higher bandwidth due to increased clock rate 2.Reduced power consumption due to 90nm fabrication technology 3.Pre-fetch buffer is doubled to 8 bits to further increase performance 4.The voltage of DDR3 SDRAM DIMM's was lowered from 1.8V to 1.5V. This reduces power consumption and heat generation, as well as enabling more dense memory configurations for higher capacities.
