Other Parts Discussed in Thread: LMK04826
Hi to everyone!
We have recently aquired a LMK04826B Evaluation Board. This borad has an external VCXO (CHVD-950) with a nominal frequency of 122.88MHz. We have unmounted this VCXO to mount an OXCO (tfc-OS240) with a nominal frequency of 10MHz.
The new OCXO has 5 ports, Vcc, Vtune, Out and GND have been directly connected to the points where the previous VCXO was connected. The fifth port is an output (Vref) that has been left open.
The point is that we are unable to achieve locking in the PLL1 and we do not know why. It is possible to make this change of VCXO? Have we forgotten something?
Thanks in advance,
