Folks, I have a need to drive the timer1 clock input at 5-5.5Mhz from a lowish impedance source of about 1.2v pk-pk. Currently I have a discrete amplifier (which seems to take excessive current) but I would prefere an IC device of some sort. Any personal preferencies for a suitable (easily sourced in the UK) device ? Peter. -- http://www.piclist.com hint: The PICList is archived three different ways.
