![]() "J M Noeding" wrote in message ... for my quite unstable counters I've got some 0.1ppm 9.6MHz VCXO's (guaranteed over temperature range -20...+20°C), the problem is that the original XO is 1MHz with 7490 divider, and now I need a divide by 96 downcounter. The VCXO drives a 74LS14, so it shouldn't be any fan out problem, but I am not aware what is the readily available divider to choose. The counter is mentioned on http://home.online.no/~la8ak/m21.htm , but it is Norwegian text The 74HC4059 (or 74HCT4059) should do the trick. It may be a bit hard to find, but will divide by any number from 3 to 16384. It is logically the same as the RCA CD4059, but I don't think the old RCA part will work at your frequency. I can't find my data book right now. 73 de bob w3otc |
