led driver to detect 10Mhz signal

[jaggu5360]

can anyone help me to design a circuit, which glows led when it detects 10Mhz lvds differential signal.

note: once it detects the signal led should on.(i mean to say that it should nt be on and off). if there is no signal, then led should off.

I would suggest an LVDS to single ended converter followed by a frequency counter and numerical comparator. Could be a simple as an LVDS inteface and a small microcontroller.

Does the signal frequency vary or is it always 10MHz?

no.frequency is constant

LVDS to single ended into some sort of peak detector could work , IF there are no other signals on the line.

You peak detector could be just a Schottky diode and a capacitor.

Could be :0)

Hi jaggu5360

Many ways are lie a head !
one of the simplest ones is using a filter for 10 MHZ and then a peak detector or a comparison network based on a simple op amp !
