AR0141CS: 1/4-Inch Digital Image Sensor

.Functional Overview

incident light. The exposure is controlled by varying the time interval between reset and

readout. Once a row has been read, the data from the columns is sequenced through an

analog signal chain (providing offset correction and gain), and then through an analog-

to-digital converter (ADC). The output from the ADC is a 12-bit value for each pixel in

the array. The ADC output passes through a digital processing signal chain (which

provides further data path corrections and applies digital gain).

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. Check the AR0141CS 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.

6. I/O signals voltage must be configured to match VDD_IO voltage to minimize any leakage currents.
