I have configured clock in sequence,
1.Write R0x0000-R0x0417 per the setup file
2.Write R0x0A01=0x20; Set user freerun mode
4.Write R0x0A02=0x03(from 0x01 to 0x03)
I read 0x11, then next sequence.
7.Write R0x0500-0x7FF per the setup file
9.Write R0x0A01-R0x0A10 per the setup file
12. write R0x005=0x01.
13.Check valid bit in 0x0D0C(bit3), because I use GPS receiver of 10M to REFB.
R0x0D0C = 0x80
Then distribution clock ouput stable. I have uploaded stp to attached file.
Now, I used this clock to supply RRU(antenna of mobile base station), I found RF frequency ppm(not stablity problem) is lager than normal(normal is ppb level, but now I have ppm level), in normal condition, it's decided by clock for RF side.
So whether I have any configurations to fix ppm problem?
