I have a FEI Communications FE-405B DOCXO looking for info.
Sales flyer and pictures of the unit here: www.n4iqt.com/fei-fe405b
The Sales flyer listed the 405A and I have the 405B don't know the difference.
A manual that shows the digital error correction via the i/o port would be
great, even better would be info on changing the frequency of the synthesizer.
I hope you realize that J513 is the ISP connector, and if you look into
the datasheet of the 89C52 you will realize that it has a read out
command. You could readout the FLASH that way. The datasheet even points
to the tool:
http://www.flashmagictool.com/
So, it could be a bit of wiring to pull the FLASH out.
You can dig a lot of useful info out of such an image.
Cheers,
Magnus
