In the modular design of the M8 connector, the energy and resources of the design can be minimized by using minimal system support and flexible pinouts to fix the direction of the electrical signal, which not only improves power, but also brings many significant Advantages include the following: Design reusability: Whether choosing a custom in-house board design or a commercially done daughter card or FMC standard, it helps to load with an existing FPGA/card right from the start To plan to new I/O, just replace the FMC module and adjust the FPGA plan slightly. Data throughput: support high signal transmission rate, the potential total bandwidth between daughter card and carrier card is 40gb/s, multi-channel I/O: provide enough I/O volume, tighten, take up small space. Compatibility: Standardized power supply, standard signal clarity, increased mutual compatibility and stability: Wide-area contacts, BGA package is selected, M8 connector anti-vibration function is added to the carrier card, and single-width modules are supported.
The FMC standard provides two standards for more flexibility in optimizing boards based on space and demand requirements. They both support single-ended and differential signaling rates up to 2GB/s, while the serial M8 connector has high signaling rates. The M8 connectors all use the same mechanical M8 connector, the only difference is what signal is actually ported, so cards with LPCM8 connectors can also be plugged into an HPC, and with proper planning, plugging in can provide many derivative features. Additionally, in addition to 68 user-defined single-ended signals or 34 user-defined differences, the LPCM8 connector provides serial transceivers, clocks, a JTAG interface, and an I2C interface as interface commands for basic smart channel management. Optional support.
In the early stages of design, M8 connector engineers tend to focus too much on the design of the entire system and place the M8 connector in the final stage of the design.
They thought the M8 connector was simple, so they could bring the design to the end. Then they got caught up in their own plans. In early planning, m8 connector engineers are often too focused on designing the entire system, placing m8 connectors in the final stage of planning. The head of product development engineering said they thought the M8 connector was simple enough to push the design to the final stage. Then they got caught up in their own plans. Too many planners rush through the final stages of m8 connector design knowing space constraints.
Although microboard-to-board m8 connectors are typically less than 1mm thick, they are also frequently used in tightly packaged applications. To deal with potential packaging issues, planners need to consider the routing on the PCB, as well as the rated wires going to the M8 connectors. “Because of the smaller pitch, the wires and wires need to be laid out a little narrower. In terms of system design, you need to consider these triggers. For example, if there is another component on the back of the m8 connector, it may not be easily accessible.
Finally, designers also need to be aware that external devices sometimes cannot handle smaller components. As the size of the M8 connector decreases, so does the current carrying capacity of the M8 connector. To compensate for the low current-carrying capacity, planners may need to increase the number of terminals.
