2. This table assumes a 33MHz time domain.
3. These specifications apply to “1.7V” processors, i.e., those with a VID = ‘00110’.
NOTES:
1. These specifications are specified at the processor pad.
2. Assumes a BCLK period of 10 ns.
3. AF is referenced to associated source synchronous strobes.
4. These specifications apply to “1.75V” processors, i.e., those with a VID = ‘00100’.
NOTES:
1. These specifications are specified at the processor pad.
2. Assumes a BCLK period of 10 ns.
