Need schematic for ANAN-10 (hermes) TCXO daughterboard
Posted: Sat May 09, 2020 12:50 pm
My ANAN-10 stopped using the internal 10MHz TCXO reference, which ends up pulling the ADC clock off by about 100ppm. It works OK using an external reference. I need the schematic (and hopefully board layout) in order to troubleshoot.
I initially suspected how the 10MHz TCXO was soldered to the board and ended up reflowing those connections but that didn't solve the problem. I am able to confirm that the 10MHz from the on-board TCXO is getting onto the board but then it disappears.
I sent email to Apache Labs support mailbox but that bounced with "mailbox full". I remember when someone posted the design for this but it was about 10 years ago and doesn't seem to be in the archives.
Thank you for your help.
