Angelia board : where's J40

Postby marc » Fri Oct 27, 2023 5:42 pm

Hi

The page 9 of the Angelia schematic shows a "J40" connector that delivers a buffered output of the 125 MHz clock. But I couldn't find it. Did someone knows where to look ?

I wish to use this clock output to feed the L.O. of a 2m transverter (144 - 125 = 19 MHz and up)

Hi Marc,

I was just looking at the schematic and some pictures I found on the net.

This looks like J40 to me (on the board):

Hi Richard

It's incredible but true ! thank you.

There is no reference on the silk mask of the board I have, but a quick test shows a direct trace between this connector and the buffer output.

I frankly could'nt imagine a 125 MHz signal going out of a Berg connector.

You made my day, thank you again & 73'
