The LC898123AXD OIS / AF driver integrates a DSP core with multiple analog peripherals for image stabilisation, auto-focus control, and H-bridge and constant-current drivers. The addition of on-chip Flash memory provides storage for the DSP program and calibration parameters, thus saving 90% of the overhead time needed to load from conventional memory on startup. This highly integrated solution enables faster implementation of OIS and AF functionality into camera modules while remaining compatible with a wide array of image sensors. Furthermore, the high level of functional integration supports the need for very thin camera modules.
The LC898123 has best-in-class current consumption, enabling improved battery lifetime. The DSP performance and flexibility allows support for various VCM actuators. The high-performance 32-bit DSP optimized for OIS/AF signal processing covers many functions, such as servo control, gyro data filtering, and host command interface. In addition, the LC898123 offers “High Level Command” function to standardize commands from the main CPU to the camera module, enabling phone developers to use standardized commands for multiple camera modules/actuators without changing CPU software.
