Note: 1. Dened in FBDIMM architecture and protocol specication.
2. Clocks dened as core clocks - 2x SCK input
3. For DDR2-667 (PC2-5300), this is measured from the beginning of the frame at the southbound input to the DDR2 clock output that latches the rst command of a frame
to the DDR2 SDRAM devices
4. For DDR2-667 (PC2-5300), this is measured from the latest DQS input to the AMB to the start of the matching data frame at the northbound FBDIMM outputs.
