OUTPUT DATA FORMAT

The AR0130 image data is read out in a progressive scan.

Valid image data is surrounded by horizontal and vertical

blanking (see Figure 8). The amount of horizontal row time

(in clocks) is programmable through R0x300C. The amount

of vertical frame time (in rows) is programmable through

R0x300A. LINE_VALID (LV) is HIGH during the shaded

region of Figure 8. Optional Embedded Register setup

information and Histogram statistic information are

available in first 2 and last row of image data.

Readout Sequence

Typically, the readout window is set to a region including

only active pixels. The user has the option of reading out

dark regions of the array, but if this is done, consideration

must be given to how the sensor reads the dark regions for

its own purposes.

Parallel Output Data Timing

The output images are divided into frames, which are

further divided into lines. By default, the sensor produces

968 rows of 1288 columns each. The FV and LV signals

indicate the boundaries between frames and lines,

respectively. PIXCLK can be used as a clock to latch the

data. For each PIXCLK cycle, with respect to the falling

edge, one 12−bit pixel datum outputs on the DOUT pins.

When both FV and LV are asserted, the pixel is valid.

PIXCLK cycles that occur when FV is de−asserted are called

vertical blanking. PIXCLK cycles that occur when only LV

is de−asserted are called horizontal blanking.
