POC-S176 User Manual 14
3.1 Introduction
The POC-S176 has an onboard display interface. The specifications and features are
described in the following section:
3.1.1 Chipset
The POC-S176 uses Mobile Intel® 945GME Express chipset for its graphic control-
ler. It supports SDVO device, and CRT monitors. The Mobile Intel® 945GM Express
Chipsets are designed for use with Intel’s next generation mobile platform, Intel®
Centrino® Duo processor technology.
The Mobile Intel 945 Express Chipset Family come with the Generation 3.5 Intel Inte-
grated Graphics Engine, and the Intel® Graphics Media Accelerator 950 (Intel® GMA
950), providing enhanced graphics support over the previous generation Graphics
and Memory Controller Hubs (GMCH’s).
3.1.2 Display Memory
Dynamic Video Memory Technology (DVMT) 3.0 dynamically allocates up to 224 MB
of system memory for graphics usage.
3.1.3 DVI Transmitter
The POC-S176 uses Chrontel CH7307C for driving its DVI Ports. The CH7307C is a
Display Controller device, which accepts digital graphics input signal, encodes and
transmits data through a DVI link (DFP can also be supported). The device accepts
one channel of RGB data over three pairs of serial data ports.
The DVI processor includes a low jitter PLL for generation of the high frequency seri-
alized clock, and all circuitry required to encode, serialize and transmit the data. The
CH7307C is able to drive a DVI display at a pixel rate of up to 165 MHz, supporting
UXGA (1600 x 1200) resolution displays.
3.1.4 Display Types
POC-S176 supports Single DVI-I jack for single monitor.
The DVI-I Jack support both DVI Digital I/F and CRT RGB signal.
Analog CRT DAC interface supports max DAC frequency up to 400 MHz, 24-bit
RAMDAC, DDC2B compliant, and resolution up to QXGA 2048 x 1536.
