PCIe® Packet Switch - 5-Port/8-lane Product: Part Numbers: PI7C9X20508GP GreenPacketTM Family Product Description Provides VC arbitration selections: Strict Priority, Round Robin (RR) and Programmable Weighted RR Supports Isochronous Traffic o Isochronous traffic class mapped to VC1 only o Strict time based credit policing Header/Data queue at each VC of each port o Four-entry non-posted request header and data (VC0 only) queue o Four-entry posted request header queue o Four-entry completion header queue o 512-byte posted write data buffer o 512-byte completed read data buffer Supports up to 256-byte maximum payload size Power Dissipation: 1.0W typical in L0 normal mode Industrial Temperature Range -40o to 85o Package: 17x17mm, 256-pin PBGA, w/1.0mm ball pitch - Pb free and 100% Green. o ® The PI7C9X20508GP is a 5-port, 8-lane, PCI Express Packet Switch specifically designed to meet the latest GREEN low-power, lead (Pb)-free system requirements, such as laptop, docking station, and other mobile or power sensitive platforms. The name of the family, GreenPacketTM, refers to Pericom proprietary power saving technology. The PI7C9X20508GP provides one upstream port supporting x4 or x1, and 4 downstream ports that support x1 operation. The flexible upstream port provides users the flexibility to expand or fanout from a wide range of I/O Bridge such as MCH, ICH, nVidia, and it is a suitable solution for HBA, Surveillance, Combo card and other applications.
