It supports transparent bridging for standard enumeration and NTB for dual-host configurations. The 4-channel DMA engine performs memory-to-memory, device-to-device, and memory-to-device transfers up to 128MB per descriptor without CPU involvement. Cut-through switching begins forwarding before a packet is fully received.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1-48<\/td><td>SerDes Lanes<\/td><td>8 PCIe lanes differential pairs<\/td><\/tr><tr><td>49-120<\/td><td>Power\/GND<\/td><td>VDD core, VDDIO, VDDA<\/td><\/tr><tr><td>121-170<\/td><td>Control<\/td><td>JTAG, I2C, SMBus, GPIO<\/td><\/tr><tr><td>171-196<\/td><td>Reserved\/Clock<\/td><td>Reference clock, SSC control<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Server expansion cards<\/li><li>Storage array controllers<\/li><li>Communication and networking<\/li><li>Dual-host failover systems<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>PEX8713-CA80BC G<\/td><td>Broadcom<\/td><td>16-lane PCIe Gen2 switch (replacement)<\/td><td>PBGA-256<\/td><\/tr><tr><td>PEX8747-CA80BCG<\/td><td>Broadcom<\/td><td>48-lane PCIe Gen3 switch<\/td><td>PBGA-625<\/td><\/tr><tr><td>Switchtec PSX-1000<\/td><td>Microchip<\/td><td>PCIe Gen3 switch family<\/td><td>Multiple<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9852","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=9852"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9852\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9852"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9852"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9852"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9852"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
