AR023ZM: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor

Functional Overview

ON Semiconductor Confidential and Proprietary

high dynamic range mode of operation where multiple images are combined on-chip to

produce a single image at 16-bit per pixel value. A compression mode is further offered

to allow the 16 bits per pixel to be transmitted to the host system as a 12-bit value with

close to zero loss in image quality.

Typical Configuration: Serial Four-Lane HiSPi Interface

Notes:

1. All power supplies must be adequately decoupled.

2. ON Semiconductor recommends a resistor value of 1.5k, but a greater value may be used for

slower two-wire speed.

3. The parallel interface output pads can be left unconnected if the serial output interface is used.

4. ON Semiconductor recommends that 0.1F and 10F decoupling capacitors for each power supply

are mounted as close as possible to the pad. Actual values and results may vary depending on lay-

out and design considerations. Refer to the AR023ZM demo headboard schematics for circuit rec-

ommendations.

5. ON Semiconductor recommends that analog power planes are placed in a manner such that cou-

pling with the digital power planes is minimized.
