Title: MedaTek MT3339 PPS accuracy before 3D-fix
Post by: Horsa on June 21, 2012, 11:18:44 AM
Q: What accuracy has the PPS (pulse per second) signal of MedaTek MT3339 before obtaining 3D-fixes?"

The accuracy of the PPS (pulse per second) signal of MedaTek MT3339 after obtaining 3D-fix is 10 ns (jitter).

The quality of the PPS (pulse per second) signal of MedaTek MT3339 before obtaining 3D-fixes (e.g. after TTFF or after obtaining 2D-Fix) is not documented, and therefore the developer should not rely upon it.
