Product description
With the continuous development of technology, high-speed serial VO technology has become a current trend to replace traditional parallel I/O technology. The fastest parallel bus interface speed is 133 MB/s of ATA7. The transfer rate provided by the SATA1.0 specification released in 2003 has reached 150 MB/s, and the theoretical speed of SATA3.0 has reached 600 MB/s. When the device works at high speed, the parallel bus is prone to interference and crosstalk, making the wiring quite complicated. The use of serial transceivers can simplify layout design and reduce the number of connectors. With the same bus bandwidth, the power consumption of the serial interface is also smaller than that of the parallel port. And the working mode of the device changes from parallel transmission to serial transmission and the serial speed can be doubled as the frequency increases.
Based on FPGA‘s advantages of embedded GB rate level and low power consumption architecture, it enables designers to use high-efficiency EDA tools to quickly solve the problem of protocol and rate changes. With the widespread application of FPGAs, the integration of transceivers into FPGAs has become an effective way to solve the problem of equipment transmission speed.
Classification
According to network management, it can be divided into network management type optical fiber transceiver and non-network management type optical fiber transceiver.
As the network develops towards an operable and manageable direction, most operators hope that all devices in their network can be remotely managed. Fiber optic transceiver products, like switches and routers, are gradually developing in this direction. The network management systems of most manufacturers are developed based on the SNMP network protocol and support multiple management methods including Web, Telnet, and CLI. The management content includes configuring the working mode of the fiber optic transceiver, monitoring the module type, working status, case temperature, power supply status, output voltage and output optical power of the fiber optic transceiver and so on. As operators demand more and more equipment network management, it is believed that the network management of optical fiber transceivers will become more practical and intelligent.
Optical fiber transceivers break the 100-meter limitation of Ethernet cables in data transmission. Relying on high-performance switching chips and large-capacity buffers, while truly achieving non-blocking transmission and switching performance, they also provide balanced traffic, isolation of conflicts and Error detection and other functions ensure high security and stability during data transmission. Therefore, for a long period of time, fiber optic transceiver products will still be an indispensable part of actual network construction. In the future, fiber optic transceivers will continue to develop in the direction of high intelligence, high stability, network management, and low cost.
The high-speed transceiver makes it possible to transmit a large amount of data point-to-point. This serial communication technology makes full use of the channel capacity of the transmission medium. Compared with the parallel data bus, it reduces the required transmission channel and the number of device pins, thereby greatly reducing the communication cost. A transceiver with excellent performance should have the advantages of low power consumption, small size, easy configuration, high efficiency, etc., so that it can be easily integrated into the bus system. In the high-speed serial data transmission protocol, the performance of the transceiver plays a decisive role in the transmission rate of the bus interface, and also affects the performance of the bus interface system to a certain extent. This research analyzes the implementation of high-speed transceiver modules on FPGA platform, and also provides a useful reference for the implementation of various high-speed serial protocols.
