CH9005 is an USB 2.0 HS/FS and UVC compliant camera controller, The built-in extreme low-power transceiver provides the superior compatibility with USB host and the best quality for image applications.
— USB 2.0 Controller CH9005 integrates USB 2.0 transceiver that is optimized for high performance data transfer rate, high speed MCU and DC-to-DC regulators, sensor controller, color processing and noise reduction into a single chip
— Image Signal Processing Unit UVC defined image processing functions are supported by using sensor's ISP engine. CH9005 supports Gamma/Hue/Saturation/Contrast/Brightness engines processing functions. These functions are very useful to compensate intrinsic inaccuracy in lens and image sensor to get better image quality.
— Image Sensor Interface CH9005 have the programmable 8-bit video data bus with general serial control interface for video transfer/control with target CMOS image sensor. It can support most available CMOS sensors from VGA (640x480) to UXGA (1600x1200) resolution.
— Embedded MTP Unit CH9005 supports both the internal MCU program ROM and external serial EEPROM interface and embedded MTP Unit it can be updated the sensor setting and ISP tuning functions several times without external storage component and configurable vendor ID, product ID and serial number from Multiple-Time Programmable (MTP).
— Built-in Regulator CH9005 integrates 3 regulators to save BOM cost and PCB area. One regulator is designed to convert 3.3V to 2.8V for sensor pixel power. One regulator is designed to convert 3.3V to 1.5V-to-3.1V for sensor I/O power, the other one regulator is designed to convert 3.3V to 1.2V core power.
— Wide range system clock output CH9005 can be programmable system clock output for performance and power saving. Additional clock output with various clock speed ranged up to 96MHz is provided for video capture module
