SVS
NOM
refers to the nominal SVS voltage which is set between 1.0 V and 1.15 V at the factory for each individual device. Only the unique SVS
NOM
value in each chip may
be used for 401 MHz to 450 MHz operation of that chip. This spec lists the possible range of the SVS
NOM
values for all devices. The initial VDD_INT voltage at power on is
1.1 V nominal and it transitions to SVS programmed voltage as outlined in Engineer-to-Engineer Note “Static Voltage Scaling for ADSP-2148x Processors” (EE-357).
