Post by thread:Re: Divide by 13 chip?

Hi all, My uC async serial port doesn't provide the baud rate clock. I've got an IRDA link that I want to run at 38.4k Baud, so the IRDA controller needs a 38.4k * 16 Hz clock. The most efficient solution might be to take the uC clock at 8MHz and divide by 13. Does anyone know of a single chip solution to divide by 13?

Any resetable counter from TTL/CMOS family will solve your requirement. You just need to reset him at right moment. Vasile On Sun, 18 Feb 2001, Thomas C.
