Hi
We are using LMK04832 in design,
CLKIN0 - 10MHz (OCXO), DC Coupled Input as shown in below circuit,
PLL1 Led doesn't come up, assuming PLL1 fails to Lock, But PLL2
OSCIN- 100MHz VCXO (Differential)
DC Coupled CLKINx
Attaching the LMK TICS file for reference
Another board with AC Coupled CLKINx is able lock & we could see lock led of PLL1
AC Coupled CLKINx
Please suggest.
Attached DC Coupled config file
