16.2. Frequency
Last table on previous page shows already that we can adjust the frequency tw. needed resistor also with
different current mirror IRCint / IRext. Please contact EM Marin directly when ordering EM6605 if you would like
to profit this possibility.
Next figures show the frequency dependence on
Rext when IRCint / IRext = 1/5
