Other Parts Discussed in Thread: USB2ANY, LMK05318B
Hello Team,
Would you be able to help resolve an issue a customer is seeing using the 1-PPS default configuration TICS Pro configuration with the LMK05318BEVM? The status is showing LOFL and LOPL.
The test setup is connected such that a GPS module with 1PPS output is connected by SMA to the PRIREF_P input jack on J17 as shown in the EVM user guide. All jumpers are connected as recommended in the user guide with the one difference being the USB2ANY voltage being jumped to the VIN1 pin on J13.
Below is the oscilloscope captured 1PPS waveform 10% duty cycle.
The TICS Pro configuration is the 1PPS Default Configuration for the LMK05318B pre-loaded in TICS Pro V1.7.2.0
Below is the status page showing the LOFL and LOPL indicators.
Please let me know if you need any more information. I have not attached the .tcs file because it comes standard in TICS Pro.
Can you help us understand why it would not be locking and what can be done to resolve this?
Thank You,
Jacob Butler
P.S. I was also considering this thread in E2E, but it was unclear if an alternate TCXO would indeed fix the clock synchronization.
