In the modular planning of the M8 connector, the energy and resources of the planning can be minimized by using the minimum system support and flexible pin distribution to fix the direction of the electrical signal, which not only improves the power, but also brings many significant Advantages, mainly include the following: Reusability of planning: Whether choosing a custom in-house board planning or a commercially completed daughter card or FMC standard, it helps to apply the existing FPGA/card loading plan from the beginning To the new I/O, it is only necessary to replace the FMC module and slightly adjust the FPGA plan. Data throughput: supports high signal transmission rate, the potential total bandwidth between the daughter card and the carrier card is 40gb/s, multiple I/O: provide sufficient I/O volume, relax, and occupy a small space. Compatibility: Standardized power supply, standard signal definition, increased intercompatibility Stability: Wide-area contact, BGA package is selected, and an M8 connector with shock resistance and single-width module support is added to the carrier card.
The FMC standard provides two scales that allow the board to be optimized or more flexibly based on space and demand requirements. They both support single-ended and differential signaling rates up to 2GB/s, while the serial M8 connectors feature high signaling rates. The M8 connectors all use the same mechanical M8 connector, the only difference is what signal is actually ported, so a card with an LPC M8 connector can also be plugged into an HPC, providing a lot of derivative functionality when plugged in, as long as it is planned properly. Additionally, in addition to 68 user-defined single-ended signals or 34 user-defined differentials, the LPC M8 connector provides serial transceivers, clocks, a JTAG interface, and an I2C interface as optional to basic Smart Platform Management Interface commands support.
In the early stage of planning, engineers of M8 connectors often pay too much attention to the planning of the entire system, and put M8 connectors in the final stage of planning. They thought the M8 connector was simple, so they were able to leave the related planning to the final stage. Then they get caught up in their own plans. In early planning, m8 connector engineers are often too focused on planning the entire system and put m8 connectors in the final stage of planning. The person in charge of product development engineering said that they thought the M8 connector was simple, so they were able to put the related planning to the final stage. Then they get caught up in their own plans. Too many planners have rushed through the final stages of m8 connector planning. Be aware of space constraints.
Although microboard-to-board m8 connectors are typically less than 1 mm thick, they are also frequently used in tight-packed applications. To account for potential packaging issues, planners need to consider routing on the PCB board, as well as additional wires attached to the M8 connector. “Because the spacing is smaller, you need to run the wires and wires narrower. When it comes to system planning, you need to account for these flip-flops. For example, if there is another component on the back of the m8 connector backwards, it may not be easily accessible. Ultimately, planners also need to be aware that externally mounted equipment is sometimes unable to handle smaller components. As the size of the M8 connector decreases, the current carrying capacity of the M8 connector also decreases. To compensate for the low current carrying capacity problem, planners may need to increase the number of terminals.
