transceiver is a device for signal conversion, usually refers to optical fiber transceiver. The emergence of optical fiber transceivers converts twisted pair electrical signals and optical signals to each other to ensure smooth transmission of data packets between the two networks. At the same time, it extends the transmission distance limit of the network from 100 meters of copper wires to 100 kilometers (single mode fiber).
With the continuous development of technology, it has become a current trend for high-speed serial VO technology to replace traditional parallel I/O technology. The fastest parallel bus interface speed is 133MB/s of ATA7. The transmission rate provided by SATA1. 0 specification released in 2003 has reached 150MB/s, and the theoretical speed of SATA3. 0 has reached 600MB/s. When the equipment works at high speed, the parallel bus is prone to interference and crosstalk, making the wiring quite complicated. The use of serial transceivers simplifies layout design and reduces 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 equipment changes from parallel transmission to serial transmission, and the speed of serial can be doubled with the increase of frequency.
Based on FPGA, it has the advantages of embedded Gb rate level and low power consumption architecture, which enables designers to use high-efficiency EDA tools to quickly solve the problem of protocol and rate changes. With the wide application of FPGA, the integration of transceiver in FPGA has become an effective way to solve the problem of equipment transmission speed.
