shiva garg Posted November 9, 2005 Report Share Posted November 9, 2005 Hello everybody i am working on IR transmitter based on 555 timer and i am succesful in making it but i want to use some other timer because frequency response of 555 timer is not stable. So can any one suggest me some other timerThanks in advance Quote Link to comment Share on other sites More sharing options...
audioguru Posted November 9, 2005 Report Share Posted November 9, 2005 Hi Shiva,The frequency stability of a 555 is pretty good when it has a supply bypass capacitor located close to it. Its stability is probably much better than the bandwidth of your receiver.An extremely stable crystal oscillator can be made with a CD4060 oscillator/divider IC. ;D Quote Link to comment Share on other sites More sharing options...
