AR0237CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor

Functional Overview

high dynamic range mode of operation where two images and taken using different

exposures. These images are output in from the sensor and the ISP must combine them

into one high dynamic range image.

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 AR0237 demo headboard schematics for circuit recom-

mendations.

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

pling with the digital power planes is minimized.
