When calculating PLL loop filter values, one need to know the phase
detector gain in mA/Hz for a "charge pump phase detector". Very often
the charge pump current is defined if you are using a synthesiser chip.
My question is therefore: What is the relationship between phase
detector gain in mA/Hz and charge pump current in mA?
I often see in literature that they define the ratio between phase
detector gain and charge pump current as a 1:1 ratio. But is this
really correct?
