Make up the blank of the mid-range connector selection, US OPAL Kelly launches the Syzygy specification interface for the FPGA module

We encounter various expansion interface types when designing and using various development boards, such as the PMOD interface launched by Digilent, Industrial Standard FMC (FPGA Mezzanine Card) interface connector, etc. The interface connector type will directly affect the transmission performance of the signal. OPAL Kelly announced that the Syzygy open I / O interface standard is launched, which is a interface type between the cost and performance between the PMOD interface connector and the FMC interface connector, Opal Kelly's slogan is also "GoldIlock" (Just right)". Figure 1: Opal Kelly Syzygy Interface Expansion Based on Xilinx Zynq SoC The Syzygy Interface Specification defines two forms of connector: The standard Syzygy connector supports 28 single-ended impedance control signal transmission, 16 of which can be used for differential pairs of interface standard (LVDS) signals, and their pin is 0.8mm. Transceiver Syzygy Connector supports data transfer of the four-channel Gigabit transceiver, and supports the transmission of 18 single-ended signals, the pin spacing of the pin is 0.5mm, and the transceiver Syzygy interface is the JESD204B data acquisition, SFP + transceiver Scenes that require high speed serdes (string and transformation) operations. Figure 2: Interface connector selection reference given by OPAL Kelly From the figure, you can see that the Syzygy interface connector provides new options to some application scenarios, and the number of PMOD interfaces in Dizhi PMOD interface is low, but the signal transmission performance is poor, and it is not suitable for some signal delays. Strictly high-speed transmission. The FMC interface connector pin has a high signal transmission performance, but the device cost is high. The syzygy interface standard made up for the blank of the mid-range connector selection, which undoubtedly brought the gospel to the engineer. In order to promote the Syzygy interface, OPAL Kelly will continue to launch an open source card based on the Xilinx Zynq SOC device, apply the Syzygy interface to more products, provide design reference for the majority of engineers, and believe that it will be welcomed by the majority of engineers.
