LMK00105: Connection between two LMK00105SQE

Ryotaro Fukui

Part Number: LMK00105

Hello team,

I received a question from my customer about the connection between two LMK00105SQE. It would be helpful if you could check the customer's connection and see if it works properly and give us some advice.

They are willing to connect LMK00105SQE CLKOUT4 pin with LMK00105SQE CLKIN pin by connecting capacitor 0.1uF in series between them. {LMK00105SQE -- |0.1uF| -- LMK00105SQE}

Their question is described as follows:

Question 1: Is it OK to have a direct connection like a regular LVCMOS connection? Or is a capacitor [0.1uF] required?

Best Regards,

Ryotaro Fukui

Hi Fukui,

For AC connection, use the connection shown in datasheet figure 6. For DC connection, use the connection shown in datasheet figure 7.

Kind regards,
Lane

Hi Boyd,

So I can use that figure as a reference for this type of connection too.

This advice has solved the customer's concern, so I would like to declare this question closed. Thank you for your prompt response.

Best Regards,
