We have been using I3G4250DTR for 5 years in our production parts. We have been noticing some recent issues with the I3G4250DTR in that some boards are not sending data (DRDY) at all, or the data is intermittent (less than the 100 Hz data rate). It is happening on about 10% of our boards.
The design hasn't changed in the last 5 years. We are suspecting the PLL filter must be causing the issues. We used the recommended parts as per the datasheet. Is there anything we can do to troubleshoot the issue? How sensitive are the values for the PLL? Is there something in the PCB design that could cause the issue (the PCB design has been the same for the last 5 years).
Any help would be greatly appreciated.
