Loop filter values for 50kHz and 25kHz PLL reference frequencies

Is there any information available on recommended loop filter values for 50kHz and 25kHz PLL reference frequencies?  We have info for 100 and 125kHz (see attached). Barring that, the phase detector + charge pump as a unit (V/ radians) would be helpful.

Hi Tells,

the ST25RU3993-HPEV is using the 50 kHz reference. Therefore you can refer to the component values used there. Note that also register 0x12 needs to be set accordingly.

Cheers,

B
