46 / 86 page Intel Desktop Board DP43TF Technical Product Specification 46 2.2.2.2 Add-in Card Connectors The board has the following add-in card connectors: • One PCI Express 2.0 x16 connector: ⎯ Supports PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction (500 MB/s total). The maximum theoretical bandwidth on the interface is 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when operating in x16 mode. ⎯ Supports PCI Express 2.0 frequency of 2.5 GHz resulting in 5.0 Gb/s each direction (1000 MB/s total). The maximum theoretical bandwidth on the interface is 8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when operating in x16 mode. • PCI Express x1: three PCI Express x1 connectors. The x1 interfaces support simultaneous transfer speeds up to 250 Mbytes/sec of peak bandwidth per direction and up to 500 MB/sec concurrent bandwidth. • PCI Conventional (rev 2.3 compliant) bus: three PCI Conventional bus add-in card connectors. The SMBus is routed to all PCI Conventional bus connectors. PCI Conventional bus add-in cards with SMBus support can access sensor data and other information residing on the board. Note the following considerations for the PCI Conventional bus connectors: • All of the PCI Conventional bus connectors are bus master capable. • SMBus signals are routed to all PCI Conventional bus connectors. This enables PCI Conventional bus add-in boards with SMBus support to access sensor data on the board. The specific SMBus signals are as follows: ⎯ The SMBus clock line is connected to pin A40. ⎯ The SMBus data line is connected to pin A41. 2.2.2.3 Auxiliary Front Panel Power/Sleep LED Header Pins 1 and 3 of this header duplicate the signals on pins 2 and 4 of the front panel header. Table 20. Auxiliary Front Panel Power/Sleep LED Header Pin Signal Name In/Out Description 1 HDR_BLNK_GRN Out Front panel green LED 2 Not connected 3 HDR_BLNK_YEL Out Front panel yellow LED |
