For a package junction to case thermal resistance of 14 C/W.
For reliability reasons the long-term current from any pin may be limited to a lower value
than stated here.
For a package junction to case thermal resistance of 14 C/W.
The nominal input clock frequency must be 16.368 MHz for the DSP module to function cor-
rectly with the GPS satellites.
