3. AF is referenced to associated source synchronous strobes.
4. These specifications apply to “1.7V” processors, i.e., those with a VID = ‘00110’.
NOTES:
1. These specifications are specified at the processor silicon.
2. BCLK period is 10 ns.
3. AF is referenced to BCLK[1:0].
4. These specifications apply to “1.7V” processors, i.e., those with a VID = ‘00110’.
