Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ExpressLane™ PEX8734-AB80BIG is a 32-channel, 8-port PCIe Gen3 switching device developed using 40nm technology. The PEX8734-AB80BIG provides multi-host PCI Express switching, enabling users to connect multiple hosts to their respective endpoints through a scalable, high-bandwidth, non-blocking interconnect. endpoints to enable a variety of applications including servers, storage, communications and graphics platforms. In addition to a large channel/port count, the device offers two NT ports and clock isolation. With backwards compatibility, when designing with PCIe Gen3 switches in mixed (Gen1, Gen2, and Gen3) systems, designers can make their designs fully Gen3-enabled when migrating to next-generation endpoints. the PEX8734 is well suited for fan-out, aggregation, and point-to-point traffic patterns. the PEX8734-AB80BIG also includes PLX's proprietary The PEX8734 also includes PLX's proprietary visionPAK debug software, which accelerates time-to-market by allowing for post-equalisation viewing of the internal receive eye and access to the device's internal debug registers.
