Design Notes
Provide a clean power supply to the AR0821CS to minimize noise in the image. Use low-dropout regulators (LDOs) with low output noise and adequate decoupling capacitors (e.g., 0.1 Β΅F and 10 Β΅F) close to the VDD pins. Avoid sharing the power supply with high-current digital circuits to prevent ripple-induced artifacts.
Follow the recommended PCB layout in the datasheet for the 95-IBGA package. Ensure proper grounding with a solid ground plane and minimize trace lengths for MIPI signals to maintain signal integrity. Use controlled impedance for MIPI differential pairs (typically 100 ohms differential) and route them away from noisy components.
The AR0821CS dissipates heat during operation, especially in HDR mode. Ensure adequate thermal management by providing a thermal pad connected to a copper pour or heatsink. The operating temperature range is -30Β°C to +85Β°C, so verify that the junction temperature stays within limits under worst-case conditions.
Compliance Information
RoHS compliant per onsemi product page. Not AEC-Q100 qualified; use AR0821AT for automotive.
