UQ200 Application For Mobile Phone Camera, High-speed MIPIC-PHY.
1.Ground Connection Specifications
The UQ200 imaging sensor incorporates dual ground domains (AGND and DGND). When implementing a unified ground scheme, both AGND and DGND may share a common connection to the sensor's ground terminal.
2.I2C Interface Configuration
Integrated programmable pull-up resistors (selectable 560Ω, 1.5kΩ, or 4.7kΩ; factory default 1.5kΩ) are provided on I²C lines, referenced to DOVDD. The pull-up resistance can be dynamically adjusted through firmware control.
3.GPIO Programmable Interface
Featuring software-configurable functionality, each GPIO incorporates a 4.7kΩ pull-up to DOVDD. These pins support application-specific customization through programmable I/O settings.
4.System Ground Considerations
Designated exclusively for peripheral power distribution (system ground domain), this terminal must remain isolated from the sensor ground network to maintain proper Open/Short test capability.
5.Reserved Pin Management
Reserved for internal system use, these pins incorporate proprietary internal routing. Maintain these pins in an unconnected state - external connections or inter-pin shorts must be avoided.
