There are two items of AD9545 question as below.
- When DPLL is configured in “close loop” mode, does Free Run Tuning Word (FRTW) will affect the output frequency?
Customer found ptp4l can track to master clock via setting FRTW when set AD9542 as “close loop” or as “open loop”. But we expect FRTW cannot tune the output frequency in “close loop”. Could you help to advice it?
- Customer modify .cso file base on “AD9545_20210222_Ch0_RefA_Ch1_FRTW_SCC_AuxDPLL_RefAA_DPLL1_DPLL0.cso”. Please help to check if the configuration is correct or not. (A) Add 1 Hz in REF B (B)Add DPLL0 Profile 2. Is it suitable to set the priority of profile 2 as ‘1’? Thank you.
