phase difference to voltage convertor

[kamelian_20]

hi all

i need some circuits for defining phase difference as voltage. I mean a phase difference to voltage converter our some circuit that change the phase difference to some electrical parameter.

thanks.

For digital signals you can use XOR gate and run output through rc filter.
You can use PLL IC, most common LM565, but here are plenty of new better PLL IC's

Hi,
USe the Phase and Frequencty detector used in PLL's constructed with 2 Dff and an and gate.

hi

could you please introduce some other ICs like LM565 i cant find it in markets.
