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.
2
For reliability reasons the long-term current from any pin may be limited to a lower value
than stated here.
Operating conditions
Notes
1
For a package junction to case thermal resistance of 14
°C/W.
2
The nominal input clock frequency must be 16.368 MHz for the DSP module to function cor-
rectly with the GPS satellites.
