Note 2 of table 13 in MPC6536 hardware spec mentions: "Peak-to-peak noise on MVREFn may not exceed +/- 1% of the DC value." What is "the DC value"?
The DC value is the GVdd value.
Do you have any typical estimated numbers for running at 3.0Gsb vs running at 1.5Gbs for MPC8536? Would there be any significant power savings?
The 8536 SATA I/O power consumptions for 1.5Gb is 240 mW and for 3.0Gb is 270 mW.
