as the max038 is actually discussed here, i would like to ask a question about it too: the MAX038 may be used in slave mode, where it is synchronized to an incoming clock. as the R/C based frequency selection of the MAX038 gives a relatively unstable frequency, i would like to connect it to a pic controlled, digital frequency synthesizer as a slave, just used to generate the selected waveform. what values for C and R do i have to use to select a base frequency for the MAX038, so that the chip is able to synchronize to an incoming frequency of 0.1Hz-20MHz? thanks! tino -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
