Hi all, I'm going to do a project which needs a high frequency excitation component, the frequency will be as high as 1MHz, and the voltage range is around about 5V. Does anyone know some cheap and small microchip which supports this function? Thanks in advance for any comments. PS: writing German is really difficult for me however I can read so feel free to answer in German :-) Gnay
If you need just a stable 1MHz frequency, watch out for crystal oscillators. Available in DIL or SMD packages for down to one or two EURO.
Here are some crystal oscillators: http://www.reichelt.de/index.html?;ACTION=2;LA=2;GROUPID=3174;SID=299-Z1kawQAR0AAG6pl8Mbb9b1274268146caf490ce69a2284030 The frequenzy is fixed, not adjustable!

I guess that you are looking for a DDS-Chip (DDS = direct digital synthesis). http://www.analog.com/en/rfif-components/direct-digital-synthesis-dds/products/index.html
