The SZG-CAMERA module includes a high performance AR0330 image sensor, along with the lens and mount necessary to begin taking images. On-board regulators provide power rails necessary to run the camera and level translation is provided to maximize the available VIO range.
The SZG-CAMERA’s DNA is configured to allow a SmartVIO range of 1.8v to 3.3v. Level translation is present on-board to convert the VIO voltage at the SYZYGY port to the 1.8v used by the image sensor.
Two linear regulators are present on the SZG-CAMERA, one at 1.8v and one at 2.8v. The 2.8v is required for the pixel array.
Pixel information from the image sensor is communicated back to the carrier through a HiSPi interface. Configuration of the image sensor is accomplished through a series of registers programmed through an I2C connection. A series of single ended LVCMOS signals are also used to communicate with the sensor. Level translation is included for the I2C and LVCMOS signals, allowing the SZG-CAMERA peripheral to operate across a wide range of VIO voltages.
The HiSPi interface consists of 4 differential pair data lines and a clock. The HiSPi data and clock lines use an SLVS/HiVCM voltage standard that is LVDS compatible. All HiSPi signals are output from the image sensor to the FPGA, internal termination must be used on the FPGA to ensure signal integrity.
The following I2C register settings (set in order) will setup the image sensor with a set of default settings that will work for most environments. More information on each register itself can be found in the image sensor documentation.
Lens and Lens Holder (included with SZG-CAMERA)
A high-quality glass lens, plastic lens holder, and mounting hardware are included with the EVB1005. The part and supplier information is listed below. Sunex also has a higher-quality lens available with better optics, the DSL944.
Autofocus Lens Mount (optional accessory)
The SZG-CAMERA is designed to be compatible with the M3-F series of autofocus lens mounts from New Scale Tech. Level translation is provided for the SPI and 2-wire interfaces on the autofocus lens mount to translate from the VIO voltage of the carrier to 3.3V I/O required by the autofocus lens mount.
Note that none of the components related to the Autofocus module are placed by default on boards sold by Opal Kelly Inc.
