[N8VEM: 17566] 1.8432MHz oscillator

[Bob Devries]

Hi Gang,

It seems to me that a half-can 1.8432MHz oscillator for CLK_UART is made of unobtainium at least on this side of the pacific. None of the local suppliers have them.

Looking at the PCB, there's room to use a full can oscillator there. Should the next version use a full can, or allow for either format?

I'm going to have to jury-rig a full-can oscillator into the available space.

I think I commented about that already... 16550 can work with a quartz resonator instead of the oscillator, it will need a couple of load capacitors and a 1 mega-ohm resistors. See the datasheet.

Bob,

With a little insulating tape underneath, and a socket with the pins
trimmed, I used a full-can 1.8432Mhz oscillator on the SBC v2.

Sometimes you can get one size oscillator but not the other. It is
advantageous to be able to order parts from a minimum of different
suppliers.
