Electrical Characteristics
3.7.1
When powering up the device, V
more than the V
bypass clock mode because the internal versions of PLLCFG[0:1] and RSTCFG are not powered and
therefore cannot read the default state when POR negates. V
pin (V
applies during power up only. V
3.7.2
The 1.5 V V
power supply rises above 2.0 V. This ensures that digital logic in the PLL for the 1.5 V power supply does
not begin to operate below the specified operation range lower limit of 1.35 V. Because the internal 1.5 V
POR is disabled, the internal 3.3 V POR or the RESET power POR must hold the device in reset. Since
they can negate as low as 2.0 V, V
POR negate.
3.7.3
The only requirement for the power-down sequence with V
its operating range, V
increases to its operating range. This ensures that the digital 1.5 V logic, which is reset only by an ORed
POR and can cause the 1.5 V supply to decrease less than its specification value, resets correctly. See
