hi everyone..
anybody know is it possible to multiply a sq wave frequency by 10 using an IC????... i need to multiplt 5Khz to 50Khz....preferably TTL IC....
If your 5khz is very rich in harmonics you can use an amp tuned to 50khz to pick off the harmonic you want. If this is too weak you use a chain of harmonic amps. Example: amplify 10khz, square it up and then amplify 50khz. It's an old technique not needed these days.

thats interesting, so maybe a 555 generating 5 khz and a chaing of op amps with LC circuits ? that have such a high gain that the output will still be square ?
Sure just use these.
The LM2907 is a frequency to voltage converter.
The LM566 is a voltage to frequency converter.
I have used this circuit to change the slow speed pulse rate coming off of the older style automotive speed sensors to a high speed signal that the newer drivetrain computer control units use. (Custom retrofit of new computer controled drivetrains in an older classic non computer controled vehicals)
Its acurate and reliable plus has a tuneable and adjustable multiplier ratio.
