See Figure 10 on page 33 for a graphical representation of the

VCC_CORE waveform.

Table 13. VCC_CORE AC and DC Characteristics

Symbol	Parameter	Limit in Working State	Units
VCC_CORE_DC_MAX	Maximum static voltage above VCC_CORE_NOM*	50	mV
VCC_CORE_DC_MIN	Maximum static voltage below VCC_CORE_NOM*	–50	mV
VCC_CORE_AC_MAX	Maximum excursion above VCC_CORE_NOM*	150	mV
VCC_CORE_AC_MIN	Maximum excursion below VCC_CORE_NOM*	–100	mV
tMAX_AC	Maximum excursion time for AC transients	10	∝s
tMIN_AC	Negative excursion time for AC transients	5	∝s

Note:

* All voltage measurements are taken differentially at the COREFB/COREFB# pins.
