Anyone know a specific electronic component which gives high freq. excitation?

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 :-)

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:

The frequenzy is fixed, not adjustable!

I guess that you are looking for a DDS-Chip (DDS = direct digital 
synthesis).
