Design-in
In order to obtain good performance with UBX-G7020 chip design, there are a number of points that require
careful attention during the design-in. These include:
Power Supply:
Good performance requires a clean and stable power supply.
Interfaces:
Ensure correct wiring, rate and messages setup on the chipset and the host system.
Antenna interface:
For optimal performance seek short routing, matched impedance and no stubs.
RF front-end:
Use an external LNA if your design doesn’t include an active antenna and optimal performance is
important.
Clock/ Oscillator:
A stable clock is essential for GPS/GNSS performance.
Configuration:
It is mandatory for stable operation that all the configurations (Low Level Configuration) of the UBX-
G7020 are set properly.
