Hi Group,

I have a crystal marked 100MHz, it the smaller package found in the CBs.

What I want to do is connect this up to a ECL or Fast TTL and get a 0 to 5
Volt
square wave output that can drive 50 ohms with 2.5 volts or more.

Anyone have a good circuit or suggestions?

Tnx de KJ4uo

It will oscillate at the fundamental, not the marked 100 MHz overtone
frequency. At 100 MHz, I'd guess that's a 7th or 5th overtone cut.
Most likely 7th, 20 MHz is about the limit for fundamental crystals.
