hi everbody

are there any differences between clock pulse oscillator and square wave osc. ? i just want to use square wave oscillator and i found DS1087LU-21H+ from maxim. could you check it please it is useful for frequency:16 mhz and amplitude value:2V

i would like to use transistor one just basic and i will connect this oscillator as a square wave generator ?
do you have any good solution ?
thank you

Why would you flash an LED at 16Mhz?

infrared red for distance measurement purposes there are 6 circuit design for example photodetector, mixer .... one of them is led driver so i need 16 or 20 mhz led driver

A square-wave oscillator has a duty-cycle very close to 50%. A clock pulse oscillator could have a duty-cycle significantly different from 50%.

It all depends upon whether a 50% duty-cycle is critical to your application. In most clock applications 50% is not needed.

so, did you look at datasheet which is https://www.electro-tech-online.com/custompdfs/2009/08/DS1087L-1.pdf
what do you think it is suitable for the project?

thanks for all

yes hi blueroom
still i m triyng to do IR measurement i used sinewave but it is not useful, now i will try with squarewave
any good square wave IC suggestion ?
thank you
