(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 ensure specific performance limits.Characteristics state DC and AC electrical specifications

under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings.

Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device

performance.

(2)

All voltages are measured with respect to the relevant VSS pin unless otherwise specified. All grounds should be coupled as close as

possible to the device.

(3)

Best operation is achieved by maintaining 3.0V < A_VDD < 5.0 and 3.0V < D_VDD < 3.6V and A_VDD > D_VDD.

(4)

Typical values are measured at 25°C and represent the parametric norm.

(5)

Limits are specified to AOQL (Average Outgoing Quality Level).

(6)

Digital shutdown current is measured with system clock set for PLL output while the PLL is disabled.
