I am looking for a module to generate logic level square wave up to at least 20MHz (50 would be better) within a $100 budget. There are a number of items on eBay but none have them seem to have a proper spec. Any recommendations from experience? --=20 __________________________________________ David C Brown 43 Bings Road Whaley Bridge High Peak Phone: 01663 733236 Derbyshire eMail: dcb.home@gmail.com SK23 7ND web: www.bings-knowle.co.uk/dcb --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
