Hi Richard,
I have added a 50 Ohm buffer?to my VFO-SigGen (Si5351A) using the two 74LVC2G17 in parallel.? Actually four drivers in parallel.? See the attachment.
It works very well for me.? In the attachment there is a schematics which I use.? This is a part of a buffer amplifier for the 10 MHz distribution from Brian Dorey.? I have used a part of his PCB for a square wave output.? The measured spectrum of a VFO 200 MHz output?signal is added.
