USB3.0 ultra-high-speed interface application solution
CH569/565 integrates on-chip ultra-high-speed USB3.0 host and device controller (built-in PHY), Gigabit Ethernet controller, dedicated high-speed SerDes controller (built-in PHY, can directly drive optical fiber), high-speed parallel interface HSPI, and digital video interface (DVP), SD/EMMC interface controller, encryption and decryption module, on-chip 128-bit wide DMA design can ensure high-speed transmission of large amounts of data, and can be widely used in streaming media, instant storage, ultra-high-speed USB3.0 FIFO, communication extension, Security monitoring and other application scenarios.
Application 1
USB3.0 FIFO application, one end of the CH569 chip is connected to the main processor (FPGA, DSP, MCU, etc.) through a high-speed parallel port (3.8Gbps), or directly connected to the camera sensor through the standard DVP interface, and the other end is connected through the USB3.0 interface (UVC Or customized equipment) is connected to a host such as a computer to realize the ultra-high-speed USB3.0 FIFO function, which can be widely used in industrial cameras, USB3.0 cameras, digital video camcorders, video capture cards, medical imaging equipment, etc.
Application 2
For high-speed data stream remote transmission applications, one end of the CH569 chip is connected to the main processor (FPGA, DSP, MCU, etc.) through a high-speed parallel port (3.8Gbps), or directly connected to the camera sensor through the standard DVP interface, and the other end is connected through the Ethernet interface (RGMII An external Gigabit PHY chip supports optical fiber or network cable) to transmit high-speed data streams to remote servers. Or through the SerDes interface, only one set of differential wires can be used to transmit 90 meters (used in pairs, direct optical fiber can support longer distance transmission), which can be widely used in surveillance cameras, surveillance cameras, network cameras, etc.
Application 3
For USB3.0 to Gigabit Ethernet applications, the CH569 chip has a built-in super-fast USB3.0 interface (built-in PHY) and a MAC controller. It can add a Gigabit PHY through the RGMII interface to easily implement standard USB Gigabit network card applications (USB3.0 device mode). Or the USB end works in host mode, operates USB3.0/2.0 U disk or mobile hard disk, and connects to the network through Ethernet to realize network sharing applications of local disks. It can be widely used in USB Gigabit network cards, network shared disks, printer servers, etc.
Application 4
USB3.0 ultra-high-speed encrypted U disk application, CH569 chip has built-in USB3.0 ultra-high-speed interface, SDIO interface and AES/SM4 encryption algorithm. The USB super-speed interface is used to connect to the computer, and the SDIO interface is used to connect SD cards and TF (MicroSD) cards. SD card data can be encrypted and stored through the AES/SM4 encryption unit to implement USB3.0 ultra-high-speed encrypted U disk applications.
