Description
LVDS-USB2.0 converter unit enables you to transfer parallel output

signal from LVDS digital camera output (EIA644, etc.) into your PC via USB2.0
interface.

2.

Main Features*High-speed transfer of up to 35M byte/s via USB2
(Actual value obtained by PC’s with ICH4 host controller. Jan 2003).
(Theoretical value=60Mbyte/s)*IO interface that can be externally controlled by API is also available
LTTL: 8 bit (output), LVDS: 5 bit (option)*Size of capturing images can be altered from software conrol* The size of outer shape (PCB) is 150mm×100mm×15mm*Power consumption: 5V, below 0.5A
*Format of driver: WDM format, compatible with Windows2000/XP

Remark1:Cam_IO0-7, CTL0-3 & EXT_TRG pin are only used forcustomization (i.e. not used in standard product).

Remark2:

The standard version is 10 bits compatible. Connect cable to D9-D0.
With the Viewer Software, 8 bits data of D9(MSB)-D2(LSB) aredisplayed.
Please contact one of our sales rep. for 12 bits connection.

Image Signal
Image: Update 1 pixel by 1 clock

Size of board is 150ｍｍ×100ｍｍ×15ｍｍ.

Timing for capturing

Soft-Trigger
pclk

vd①②③④①Trigger from software. Wait for leading edge of “vd” at falling edge of “Soft-trigger”.

②

After detecting leading edge of “vd”, image data transfer is prepared.

③〜④ Transfer image for the amount of vertical pixels set.

Remark3: In external trigger mode, one transfer is automatically finalized when number of line iscounted using “hd” signal, and effective line is transferred. (applies in customization)
Remark4: Image data is latched by falling edge of pixel clock.
