Hi, I know it is not the right forum but I have no idea where else I should ask. I have bought a crystal can oscillator for a project it has 4 pins (GND, +5V, Out, Enable/Disable). But when I hooked it up to my project it did nothing so I hooked the oscillator up the oscilloscope to check it, there was only a weird wave and not a High/Low signal. (The power source is fine it is a really clean dc line). Thank you
What's the part number?
Did you put a 0.1uF capacitor between 5V and ground close to the can?
Please provide a part number and a link to its datasheet.
Is it an analog (sine) or digital (rectangle) oscillator?
This is the part number “ ECS-2200B-100”, I have put an 0.1uF cap between ground and 5V. This is the link to the data sheet https://www.mouser.at/datasheet/2/122/ecs_2200-1284324.pdf
It is a square wave oscillator.
Try putting a 10K ohm resistor between out and ground and see what the signal looks like
Your scope should have a bandwidth of 50MHz or higher
Thank you, but the wave looks still the same.
Is this on a solderless breadboard?
Is your scope ground connected right near the GND pin and is the probe right near the Out?
The scope is grounded and the probe is right near the out pin, but I have built it on a breadboard, to test it. Do you mean I should solder it?
Did you leave pin 1, the enable/disable, disconnected?
Yes it has an internal pull-up resistor but I have tried it to connect it to +5V because it is an active Low but nothing has changed.
Maybe it's simply defective.... Always buy 2 of everything!
Or, do you trust your 'scope?
Are you sure you identified the pins correctly? (The datasheet says the Enable pin can be left open.)
I have bought 5 and all of them put this weird signal out, and I really trust my scope and also I have tested it with simple binary counters hooked them up to the scope and saw nothing (that they would count)
Did you buy them from Mouser or AliCheapStuff?
I bought it from Mouser.
What's the bandwidth of your scope?
100MHz, and I have an 10MHz oscillator
It's rare but both Mouser and Digi-key sometimes put the wrong thing in the right bag.
Is the marking on the part correct?
If it is, I'm out of suggestions.
The markings are right. But Thank you for helping
