Electronics / Re: Alternative for IDT XLH536026.000000I Crystal Oscillator

Thanks for your quick reply, Daniel.

I hadn't thought of using a smaller one as a replacement.

For now, I selected the ECS-3225S33-260-FN-TR.

Once the PCBs are tested, I'll let you know how it worked out.

Best,
Mike

Electronics / Alternative for IDT XLH536026.000000I Crystal Oscillator

Hi Daniel,

We're doing a new small production run of the Miniscope.
Seems like all usual suppliers (Farnell, Mouser, Digi-Key etc.) have run out of 26MHz oscillators in size 5.0 x 3.2 mm.
Do you happen to know any sources who have these, or suitable replacements, on stock?

Best,
Mike

Electronics / Re: Flickering excitation LED with longer coax cable

« on: August 12, 2016, 12:19:54 AM »

We have 10 scopes in use with 3m coax cables. No problems with 9 of them.
Recently I replaced the LED on the 10th one because it was flickering and getting dimmer during a short period of operation. My guess is, the LED was degraded during the soldering process, maybe it got too hot. Some LEDs are very sensitive to that. Problem seems solved now.
