LMK04133: if this IC can support that it can be input from both the positive end and negative end

Gary Zeng

Part Number: LMK04133

We want to input clocks to Clock_in0, Clock_in1 and OSCin in single-ended mode. The description seen in the data sheet requires input from the positive terminal, but the schematic diagram and instructions given in the evaluation board manual indicate that it is input from the negative terminal. enter. Does this mean that when using single-ended mode, input from both the positive and negative terminals can be used?

Gary,

Yes. Both the P or N input can be driven by the single ended signal, with the other signal being AC-coupled to ground. The datasheet is confusing when it talks about the "default configuration" when in reality, either can be used.

Regards,

Will
