Intel® IQ31244 Customer Reference Board

5.0SATA Interface

On the IQ31244, the Intel® 31154 133 MHz PCI Bridge interfaces with four Intel® 31244 PCI-X to Serial ATA Controllers on the 64-bit data secondary PCI-X bus clocking at 100 MHz. The 31244 chip transmits and receives commands to one of the four Serial ATA channel with speeds of

1.5Gb/s and 8b/10b encoded data. Each 31244 controller (U27–U30) has four channels. There is a total of sixteen SATA signal connectors (J21–J36) on the IQ31244 board. The IQ31244 is configured for Direct Port Access (DPA) mode to allow independent control of the SATA devices.
