Tool/software:
Hi Experts, I have the LMK05318B on custom board and it works very well.
XO OCXO 24.576MHz
Ref1 GPS PPS
Ref2 IEEE1588 PPS optional
out1 25MHz
out2 10MHz
out7 PPS
When Ref1 is validated the output starts folowing. In one minute LOFL_DPLL goes low and after a while we have also DPLL phase lock, LOPL_DPLL low.
Tuning word history update HIST bit flashes periodic. R14 now is mostly 0x00 except for HIST bit.
I have adjusted the OCXO +0.1 PPM by purpose to see the difference between holdover and freerun.
But when i interrupt gps reception the LMK always falls to XO ppm offset instead of calculated averaged historical offset.
Expected the LMK holds the locked freq offset as long as no ref input in valid.
What am i doing wrong?
