Crystal Selection for Propeller

Larry Martin

I am bringing up my first Propeller board and am having some trouble with the crystal.

I ordered the DigiKey X1050-ND 5 MHz, 20 pF, 49 uS, which seemed to have the same specs as the crystal sold for Propeller on Parallax.com:

but my board will not work unless I plug in the crystal from my Parallax Propeller demo board. That crystal just says "5.0000". The crystal sold by Parallax says "5.00ECSR". The ones I bought from DigiKey say "5.00ECSXR".

Can someone explain the difference between these crystals, or maybe recommend a DigiKey or other part number?

Thanks,
Larry

Should work. I have these that I bought in Digikey and they work well.

P/N: X989-ND

Thanks, Luis. This morning, I got back on task and tried the other crystal from that DigiKey order, and it worked ok. Guess I got a bad one.

X1050-ND works with Propeller.
