ALINX FL0214 FMC Binocular MIPI Camera Module

FL0214 FMC Binocular MIPI Camera Module

Part1: FL0214 Binocular MIPI Camera Module General

Description

ALINX FMC Binocular MIPI Module FL0214 is a 2-channel 1.3 megapixel CMOS camera module with MIPI interface. The FL0214 module has two MIPI interface camera modules. The camera module uses Sony’s CMOS sensor chip IMX21. The camera has a maximum resolution of 4224 (horizontal) x 3120 (vertical). The camera’s MIPI signal is converted to an LVDS signal by the MC20901 chip to the FMC interface for FPGA sampling. The module has a standard LPC FMC interface for connecting to the FPGA development board. The FMC connector model is: ASP_134604_01

Part 2.2: FL0214 Binocular MIPI Camera Module

FL0214 Binocular MIPI Camera Module, make the lens motor drive and CMOS sensor chip on a module. The panel size of the module is 8.5mm*8.5mm and the viewing angle is 80.7°. CMOS uses SONY’s IMX214 sensor with a resolution of 130,000 pixels. The module can control the internal registers and control the motor through the I2C bus to achieve focus adjustment. The I2C write device address is 0x20 and the read device address is 0x21. Refer to the documentation for the IMX214 for specific information on the registers. Refer to the documentation of the IMX214 for specific register information.

Part 2.3: MC20901 5 Channel FPGA Bridge IC for MIPI D-PHY

Systems and SLVS to LVDS Conversion

Since the interface of the FPGA does not directly support the level standard of the MIPI D-PHY, a bridge chip MC20901 is required for level conversion. The MC20901 is a 5-channel MIPI D-PHY circuit conversion chip. The 4-channel LANE data output by the camera and the MIPI signal of the 1-channel clock LANE are converted into LVDS differential signals supported by the FPGA chip through the MC20901 chip. The following Figure 2-2 shows the functional block diagram of the first CHA channel of the MC20901:
