UCD3138: Phase Locked Loop Design implementation with UCD

Tool/software:

Hi Champ,

I am asking for my customer.

They want to implement the phase-locked loop (PLL) technique on the UCD3138 for AC input detection, is there any source code / app. note that could be referred to ?

Only find similar app. note from C2000 on website https://www.ti.com/lit/an/sprabt3a/sprabt3a.pdf, checking on similar design from UCD team.

Please share any UCD ref. design that do use the phase-locked loop (PLL) technique if we have it.

Thanks and regards,

Johnny
