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

Functional Overview

Figure 3:

Typical Configuration: Parallel Pixel Data 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 serial interface output pads and VDDSLVS can be left unconnected if the parallel output inter-

face 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.

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

7. The EXTCLK input is limited to 6-48 MHz.
