Part Number:LMX9830
Hello, we're still using the LMX9830 on one of our older products (I realize its now NRD) and lately have been receiving complaints from the field on units not pairing or inconsistent pairing problems. Aaron answered questions I sent concerning the device revisions thinking maybe we had some old devices. Spending a lot of time lately trying to narrow down the problem. What I see now on over 20 units is that they won't pair up if the temperature is on the chilly side (below 50 degrees F). I don't get anything out on the VCO OUTPUT pin (F8) until the 9830 is brought up close to room temperature. Then it pairs up with no problem. Has anyone heard or seen this problem? Could this be a solder problem (cold / weak connections to the balls)?
Any help appreciated.
