7.3.3.1

10-bit mode

In this section, the read-out timing for the default 10-bit mode is explained. In this mode the

maximum frame rate of 340 fps can be reached.

For simplification, the timing for only one LVDS channel is shown in every case in the following

paragraphs:

•

16 Output Channels

•

8 Output Channels

•

4 Output Channels

•

2 Output Channels

16 output channels:

By default, all 16 data output channels are used to transmit the image data. This means that

an entire row of image data is transferred in one slot of 128 pixel periods (16 x 128 = 2048).

This results in a maximum frame rate of 340 fps.

8 output channels:

When only 8 LVDS output channels are used, the read-out of one row takes (2*128) + (2*1)

CLK_IN periods. The maximum frame rate is reduced with a factor of 2 compared to 16

channels mode.

4 output channels:

When only 4 LVDS output channels are used, the read-out of one row takes (4*128) + (4*1)

CLK_IN periods. The maximum frame rate is reduce with a factor of 4 compared to 16

channels mode.
