Information

At the sensor output, all channels are bit and word aligned with minimal skew (per readout

side). Yet, it is advised to perform bit-alignment on the receiver to optimize the sample point

of every data channel.

Reading out a frame is done row-by-row. The pixels of a row are evenly distributed along all

enabled outputs. Any number between 1 and 8 DATAx_OUT channels (per side) can be

used, depending on the horizontal multiplexing settings (see section 7.6.2). DATA0_OUT is

always active. If more than 1 channel is used, additional channels are enabled from left to

right.

Using the OB_OUT channel is optional, because by default the row OB corrections (using the

OB columns) are done on-chip.

Low-Level Pixel Timing

●

Data is transferred serially over each channel, one complete word at a time.

●

Data is transferred either LSB bit or MSB bit first through configuration.

●

All channels are word aligned (first bit of all channels sent during same CLK_OUT

cycle).

This results in the timing diagram in the figure below (shown for 12-bit data, LSB bit first).

Control Channel

Like all other data channels, the CTR_OUT channel transmits its data word-based. A word

being transmitted on the CTR channel consists of a number of bits, each reflecting the status

of a certain aspect of the sensor behavior. The table below lists the function of each bit.
