Design guaranteed.
For propagation delays, “tpdh” refers to the specified signal going high “tpdl” refers to it going low. Reference Gate Timing Diagram.
Guaranteed by design; not tested in production.
Internal DAC voltage is centered 19 mV below the listed Voltage. For VR11.1/VR11.0/VR10
No DAC offset is implemented for AMD operation.
