2 of 28 april 9, 2010 idt 89HPES12N3 data sheet two smbus interfaces ? slave interface provides full access to all software-visible registers by an external smbus master ? master interface provides connection for an optional serial eeprom used for initialization ? master interface is also used by an external hot-plug i/o expander ? master and slave interfaces may be tied together so the pes12n3 can act as both master and slave 8 general purpose input/output pins packaged in 19x19mm 324 ball bga with 1mm ball spacing product description utilizing standard pci express interconnect, the pes12n3 provides the most efficient high-performance i/o connectivity solution for applica- tions requiring high throughput, low latency, and simple board layout with a minimum number of board layers . it provides 6 gbps (48 gbps) of aggregated, full-duplex switching capacity through 12 integrated serial lanes, using proven and robust idt te chnology. each lane provides 2.5 gbps of bandwidth in both directions and is fully compliant with pci express base specification 1.0a. the pes12n3 is based on a flexible and efficient layered architec- ture. the pci express layer consists of serdes, physical, data link and transaction layers in compliance with pci express base specification revision 1.0a. the pes12n3 can operat e either as a store and forward or cut-through switch and is designed to switch memory and i/o transac- tions. it supports eight traffic classes (tcs) and one virtual channel (vc) with sophisticated resource management. this includes system selectable algorithms such as r ound robin, weighted round-robin, and strict priority schemes guaranteeing bandwidth allocation and/or latency for critical traffic classes in applic ations such as high throughput quad/ dual gigabit i/os, sata contro llers, and fibre channel hbas. switch configuration the pes12n3 is a three port switch that contains 12 pci express lanes. each of the three ports is st atically allocated 4 lanes with ports labeled as a, b and c. port a is always the upstream port while ports b and c are always downstream ports. t he switch operating mode, as well as an optional initialization from a serial eeprom, is selected via the switch mode (swmode[3:0]) inputs. during link training, link width is automatically negotiated. each pes12n3 port is capable of independently negotiating to a x4, x2 or x1 width. thus, the pes12n3 may be used in virtually any three port switch configuration (e.g., {x4, x4, x4}, {x4, x2, x1}, etc.). the pes12n3 supports static lane reversal. for ex ample, lane reversal for upstream port a may be configured by assert ing the pci express port a lane reverse (pealrev) input signal or through serial eeprom or smbus initialization. lane reversal for ports b and c may be enabled via a configuration space register, serial eeprom, or the smbus. figure 2 i/o expansion application memory memory memory processor memory north bridge pes12n3 pes12n3 pes12n3 i/o 10gbe i/o 10gbe i/o sata i/o sata pci express slots
