Other Parts Discussed in Thread: CDCE62005
Hi,
I'm having some problems configuring CDCE62005. My primary reference clock (PRI_REF) is 30.72MHz. But when I try to read it out from SMART MUX using output divider 3, with following register value 0x2140020, I can only see a clock around 350MHz and I can't change it's value by modifying reference divider or pre divider values, it always stays around 350MHz.
Also I wonder how equation 1 on page 11 works?
Fout = Fin x [F/(R x I x O)]
Is R output or SMART MUX in MHz and are I, O and F values of corresponding divider registers?
Also what problems can PLL staying unlocked cause?
I was also wondering do you have any ready made C or any other library/code for tuning and calculating parameters for CDCE62005?
