17 Electrical specifications
Absolute maximum ratings
Operation beyond the absolute maximum ratings may cause permanent damage to the device.
All voltages are measured referred to
GND
.
Notes
1
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.

2
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.
