1.6.9 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 Macrovision

and

RGB bypass mode which enables driving a VGA CRT with the input data.

1.6.10 Ethernet

1.6.10.1 Realtek RTL8100C Ethernet Controller

The Realtek RTL8100C(L) is a highly integrated, cost-effective single-chip Fast Ethernet

controller that provides 32-bit performance, PCI bus master capability, and full compliance

with IEEE 802.3u 100Base-T and Power Interface (ACPI), PCI power management for

modern operating systems that are cpable of Operating System-Directed Power

Management (OSPM) to achieve that most efficient power management possible. The

RTL8100C(L) does not support CardBus mode (the RTL8139C does).

In addition to the ACPI feature, the RTL8100C(L) also supports remote wake-up (including

AMD magic Packet, LinkChg, and Microsoft® wake-up frame) in both ACPI and APM

(Advanced Power Management) environments. The RTL8100C(L) is capable of performing

an internal reset through the application of auxiliary power. When auxiliary power is applied

and the main power remains off, the RTL8100C(L) is ready and waiting for a Magic Packet

or Link Change to wake the system up. Also, the LWAKE pin provides 4 output signals

(active high, active low, positive pulse, and negative pulse). The versatility of the

RTL8100C(L) LWAKE pin provides motherboards, with Wake-On-LAN (WOL) functionality.
