For supporting different voltage operating points, the following rules must be followed:
- CVDD should not exceed RVDD
- RVDD should not drop below 1.2V regardless of CVDD voltage or operating point
1. Can CVDD exceed RVDD if DVFS is not implemented (static supplies) ie. CVDD=1.3V; RVDD=1.2V ?
2. Can RVDD be operated anywhere above its Vmin=1.14V as per datasheet, or is 1.2V the actual Vmin as per above?
We have an old PCB design that is "pre-456MHz" but populated with 456MHz parts, and ties RVDD to the other 1.2V static supplies...
