simple baud rate generator

20 simple baud rate generator The generator described is a good- value-for-money alternative to the commercially available types; it uses only one CMOS-IC and provides up to leven different baud rates. Each serial data interface requires a baud rate generator: terminal, printer, tape interface ... It is often not possible to use the same generator for input and output, so it would be useful to add one to, for instance, the UART in the computer or the UART in the terminal. To keep the colts of such an addition down, we have developed a generator which uses just one IC, two resistors, one preset potentiometer and a capacitor The CMOS 4060 is a 14-stage binary counter with an internal oscillator which only requires the frequency determining RC components. As the reset is connected to earth, the counter begins to count upwards when the supply is switched on. A clock frequency then becomes available at the outputs: the higher the number of the output, the lower the frequency available ...
