Hi,
is there more any info on this ?
the LTSpice help just says PHIDET = behavoural type II phase detector, make
sure the inputs dont rise to sharply,
im not sure if its doing what I want, I was hoping to simulate the function
of the phase/frequency discriminator of something like the cd4046.

aha, after staring at the state diagram for the type II phase detector in
the 4046 i realised why its not doing what i expected, it apears it can
confuse -90' phase diference for +270'. so i need to think of something else
to use.
