DS90UH940-Q1: SETTING FOR DS90UH947-Q1 AND DS90UH940-Q1

Bang Duong

Part Number: DS90UH940-Q1

Hi all,

I need convert LVDS signal from camera Hitachi DI-SC233 to MIPI CSI-2. So my solution is : LVDS => DS90UH947 => DS90UH940 => CSI-2.

But I have some problem. DS90UH947 and DS90UH940 are dual link. I dont understand setup to use single link or dual link in datasheet.

Someone can help me about it?.

And I need design High Speed PCB. I use Altium 17.Someone can share me document about High Speed and Altium designer guide High Speed?.

Thank for reading!

Best regrads.

Are you reffering to:

Single and Dual FPD-Link III Outputs

Single Link: Up to 96 MHz Pixel Clock

Dual Link: Up to 170 MHz Pixel Clock

If so this is the FPD-Link III and single link is typically used for the lower OLDI PCLK rate. The dual link is used for the higher OLDI PCLK rate.

Hi Jeong,

When i only use 1 lane CSi-2 ( 4 data lane + 1 lane clock ) from DS90UH940-Q1, max bit rate on each data lane ( 1 of 4 data lane CSI-2) can up?.

Thanks.
