I'm looking for some recommendations... I'm looking to sample frequencies for a display - but they are in the range of 100MHz to 500MHz - much too fast for a PIC, so I'm thinking of using a prescaler to divide down the frequency. I'd like something fairly easy to work with and that has a DIP package available for experimenting, but I'm really not sure what will work best for me. Ultimately, I need it divided down far enough where I can use either a counter, or a PIC input to calculate the input frequency. any suggestions, and any sample circuitry one might know of that would help me to integrate such a beast would be most appreciated!! -Tony -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
