Intel(R) 31244 PCI-X to Serial ATA Controller Developer's Manual
The Intel(R) 31244 PCI-X to Serial ATA Controller (31244) is a single-chip
solution for a PCI-X to Serial ATA Controller. It accepts host commands
through the PCI-X bus, processes them and transmits them to one of four
Serial ATA targets. The 31244 supports Serial ATA speeds of 1.5 Gbps of
8b/10b encoded data which is equivalent to 150 MBps of raw data. The
31244 derives its Serial ATA clocks from an internal PLL with a reference
clock of 37.5 MHz. On the 64-bit PCI-X bus, when run at the maximum
frequency of 133 MHz, the 31244 supports a maximum burst transfer rate
of 1064 MBps.
