The green boards are xo adapter boards from Ian's fifo reclock GB on diya
This clock just so happened to be on one of them from another project
And I just dropped it in
Usually solder them on direct now

Is what I used

Got it Will order some.

I can ignore the OE for this clock though, correct? Only need to connect Vdd, clock output, and gnd?

yea i think oe was not connected

Got the flipflop up and working...

are you using lifep04 power yet?
if not, it is quite likely that some on board bypass film caps and possibly some of those os-con type caps could benefit
just seem to get away without them using the lifepo4 cells

with the reclocker theres two options for reclocking in your situation
either using the sdcard mck out or the soekris fpga mck out

Saving lifepo mod for last. Got some battery holders on the way to make hookup easier. Any pros and cons of using sd vs soekris mck out?

Might try to swap xpresso 22/24 clocks for tiny ndk nz2520sd clocks I got from diyinhk.

as its real easy to try
try both..

i consider both mck's to be flawed
and were probably in the domain of the lesser evil

if you take the sd clocks look at the distance between the audio frequency clocks and the ff reclock its a very long distance for a mck
also i tend to like to reclock with ff to the destination mck and i really wish it was a fixed clock solution as i think there better (thats why i put a fixed clock on my sd build)

got it.

btw. this look okay for the 32khz wiring? ive got clk output soldered and about to do the rest...

32khz

Sometings not right there
vcc is diagionally opposite gnd and clk output diagonally opposite pin1 OE

yeah i drew that wrong. vdd is opp gnd. my main concern was wether clk output was correct...
