AR0130: 1/3-Inch CMOS Digital Image Sensor

Features

Hard Standby

Hard Standby puts the sensor in lower power state; previously written register settings

are still maintained.

A specific sequence needs to be followed to enter and exit from Hard Standby.

To Enter Hard Standby:

1. R0x301A[8] = 1

2. R0x301A[12] = 1 if serial mode was used

3. Assert STANDBY pin

4. External clock can be turned off to further minimize power consumption (Optional)

To Exit Hard Standby:

1. Enable external clock if it was turned off

2. De-assert STANDBY pin

3. Set R0x301A[8] = 0

Window Control

Registers x_addr_start, x_addr_end, y_addr_start, and y_addr_end control the size and

starting coordinates of the image window.

The exact window height and width out of the sensor is determined by the difference

between the Y address start and end registers or the X address start and end registers,

respectively.

The AR0130 allows different window sizes for context A and context B.

Blanking Control

Horizontal blank and vertical blank times are controlled by the line_length_pck and

frame_length_lines registers, respectively.

• Horizontal blanking is specified in terms of pixel clocks. It is calculated by subtracting

the X window size from the line_length_pck register. The minimum horizontal

blanking is 110 pixel clocks.

• Vertical blanking is specified in terms of numbers of lines. It is calculated by

subtracting the Y window size from the frame_length_lines register. The minimum

vertical blanking is 26 lines.

The actual imager timing can be calculated using Table 4 on page 15 and Table 5 on

page 16, which describe the Line Timing and FV/LV signals.
