10.0 Electrical Characteristics
(Notes 1, 2) Unless otherwise stated
PLL_V
DD
= 3.3V, D_V
DD
= 3.3V,
BB_V
DD
= 1.8V, A_V
= 3.3V, LS_V
= 3.3V.
The following specifications apply for the circuit shown in
Figure 2
unless
otherwise stated. Limits apply for 25C. (Continued)
Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional but do not guarantee specific performance limits.
Characteristics state DC and AC electrical specifications under particular test conditions which guarantee specific performance limits. This assumes that the device
is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is given, however, the typical value is a good indication of device
performance.
Note 2:
All voltages are measured with respect to the relevant V
SS
pin unless otherwise specified.All grounds should be coupled as close as possible to the device.
Note 3:
The maximum power dissipation must be de-rated at elevated temperatures and is dictated by TJ
,
θ
, and the ambient temperature, T
A
. The maximum
allowable power dissipation is P
DMAX
= (T
JMAX
– T
A
)/

or the number given in Absolute Maximum Ratings, whichever is lower.
Note 4:
Human body model: 100pF discharged through a 1.5k
resistor.
Note 5:
Machine model: 220pF – 240pF discharged through all pins.
Note 6:
Typical values are measured at 25C and represent the parametric norm.
Note 7:
Limits are guaranteed to Nationals AOQL (Average Outgoing Quality Level).
Note 8:
Best operation is achieved by maintaining 3.0V

Note 9:
Digital shutdown current is measured with system clock set for PLL output while the PLL is disabled.
Note 10:
Disabling or bypassing the PLL will usually result in an improvement in noise measurements.
