Figure 55:

CTR_OUT Channel Bits Timing

Some notes concerning the figure:

●

EXP_L and EXP_S indicate the actual exposure time (so taking shutter lag and exposure

overlap into account)

●

The READOUT phase of the sensor (as used in section 7.2.6) is more than only FVAL. There is

some overhead time between the end of GLOB and the start of FVAL.

●

Two DVAL periods are separated by an overhead time (OT). The length of this overhead time

depends on the channel multiplexing and row time settings, but will be at least 1 word.

●

The OB data of a row of pixels appears on OB_OUT about one row time before the valid pixel

data of the same row appears on DATAx_OUT. The exact timing is evident on the control

channel. This allows external grabbing and evaluation of the OB data before the pixels of the

same row are being read. This way, corrections can be done without the need for an additional

row buffer.

●

Image statistics data is always sent via DATA0_OUT and is framed with the SVAL bit.

Information

The sensor can be operated without using the control channel. The presence of the inverted training

word on each of the LVDS output channels allows to recognize the start of data transmission. The

advantage is reduced complexity and possible power savings by disabling the CTRL channel LVDS

output, also see section 7.6.1. For more details, an application note is available.
