POC-S196 User Manual 14
3.1 Introduction
The POC-S196 has an onboard display interface. The specifications and features are
described below:
3.1.1 Chipset
The POC-S196 uses a Mobile Intel® 945GME Express chipset for its graphic control-
ler. It supports an SDVO device, and CRT monitors. The Mobile Intel® 945GM
Express Chipsets are designed for use with Intel’s next generation mobile platforms:
Intel® Centrino® Duo processor technology.
The Mobile Intel 945 Express Chipset Family come with a 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
The POC-S196 deploys Dynamic Video Memory Technology (DVMT) 3.0 to dynami-
cally allocate up to 128 MB of system memory for graphics usage.
3.1.3 DVI Transmitter
The POC-S196 uses the Chrontel CH7307C for driving its DVI Ports. The CH7307C
is a display controller device, which accepts digital graphics input signals, encodes
and transmits data through a DVI link (DFP is also 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 165MHz, supporting
UXGA (1600x1200) resolution displays.
3.1.4 Display Types
The POC-S196 supports a single DVI-I jack for a single monitor.
The DVI-I jack supports both DVI Digital I/F and CRT RGB signal.
An analog CRT DAC interface supports a maximum DAC frequency up to 400 MHz,
24-bit RAMDAC, DDC2B compliant, and resolution up to QXGA 2048 x 1536.
