User’s Manual for Advantech SOM-A2558 series module V1.00

If user wants to connect CSB to LVDS type LCD, user could reference “Advantech SOM-A255x series CSB design guide “to design LVDS Transmitter on CSB. SOM-A255x series only support 1 channel LVDS LCD panel.

The sample images of SOM-A2552, SOM-A255F series could support 4 kinds of display modes:

320x240 TFT: In SOM-A2552 & SOM-A255F module, user CAN’T verify the performance by Advantech LCD kit LCD-A057-STQ1-0. Because SOM-A2552 & SOM-A255F supports 320x240 TFT mode, but LCD-A057-STQ1-0 is 320x240 STN panel.

640x480 TFT: user could verify the performance by Advantech LCD kit LCD-A064-TTV1-0.

800x600 TFT: user could verify the performance by Advantech LCD kit LCD-A104-TTS1-0.

1024x768 TFT: user could verify the performance by Advantech

LCD kit LCD-A150-TTX2-0.

Except 320x240 TFT mode, user could verify the LCD-out function by Advantech LCD kit. Advantech LCD kit LCD-A057-STQ1-0 is 320x240 STN type LCD, not TFT type, so user couldn’t verify the 320x240 TFT function by sample images.

The sample images of SOM-A2558 series could support 4 kinds of display modes:

320x240 STN: User can use Advantech LCD kit LCD-A057-STQ1-0 to evaluate the LCD-out performance of SOM-A2558 platform.

640x480 TFT: User can use Advantech LCD kit LCD-A064-TTV1-0 to evaluate the LCD-out performance of SOM-A2558 platform.

2.2.11Zoom Video (ZV) port

SOM-A255F & SOM-A2552 series ZV port comes from SM501. SOM-A2558 series don’t support the function. ZV Port can interface with video decoders, such as NTSC/PAL decoders, MPEG-2 decoders, and JPEG Codec. The ZV Port supports resolutions up to 1280x1024. It directly accepts digitized RGB or YUV signals, and does not accept analog signals.

In 16-bit mode, the ZV [15:8] signals are the most-significant eight video pixel inputs. In 8-bit mode, these signals are not used. In 16-bit mode, the ZV [7:0] signals are the least-significant eight video pixel inputs. In 8-bit mode, these signals are the only eight video pixel inputs.

About how to wire the ZV port with NTSC/PAL decoders, please check “Advantech SOM-A255x series CSB design guide “.

2.2.12 System Reset Interface

SOM-A255x series all supply 3 kinds of System reset interface as following:

ØnRESET : hardware reset input pin. The pin is pulled high in SOM-A255F. The pin is triggered by signal falling edge.
