I configured the register using I2C, now, I generate register forms using AD9548 Evaluation software.
My SYSCLKP is TXCO(KT3225P-19.2MHZ)
1.Reset the AD9548,
2.Config all registers,
3.Wait DPLL phase lock(using 0xD0A),
but I found that 0x0D0A is always 00. So I check SYSCLK locked register. I found that it's not stable.
Now, some register value is:
silicon number: C3(the value is strange, because the datasheet is C6)
0xD01: 01, it means status of not stable, locked. I change system clock stability period from 1ms to 64ms, but it always is not stable.
So I want to know some possible reasons for my design, including hardware and registers. I'll appreciated for your reply. Thanks.
