I have to reproduce an existing circuit. When I was looking for the components, some of them are obsolete and so I need to find an alternative. I am having a 15.36MHz Crystal Oscillator (TCO-21A 8) with 4 pins (Pin1 = N/C; Pin7 =GND; Pin8 = Output ;Pin14 = Vcc). Pin 7 is connected to GND, Pin 14 to +5V and Pin 8 is connected to the clock pin of Dual D Flip Flop 74HC74D.
I could not find a THT 15.36MHz Oscillator with 4 pins. Can anyone tell me whether I can use a two pin CRYSTAL 15.3600MHZ(like this https://www.digikey.ca/en/products/detail/cts-frequency-controls/ATS15A/280193) Or is there an alternative for the old one? I would be also very happy if anyone can explain me the difference between both.
As far as I understood, Crystal oscillators are the one usually with 4 pins with Vcc, GND, OSc output and enable pin and Quartz cyrstals are the ones with 2 pins that are supposed to be connected to the OSC1 and OSC2.
What happens if I use a KX0-01-1 (16MHz) Crystal clock Oscillator in my case. Will a 16MHz instead of 15.36MHz make a big difference?
Thanks
Matt
