LMK00306: Cascade connection

Hirotaka Matsumoto
Guru 27525 points
Part Number: LMK00306

Hi all

Would you mind if we ask LMK00306?

<Question1>
LMK00306 doesn't have input termination resistance, right?
So, does it require external termination resistance at input?

<Question2>
The customer would like to use two LMK00306s with cascade connection like as follow.
Example) Clock input ->  Clkin ①LMK00306  Clkout -> Clkin ②LMK00306
In this case, does it reguire AC coupling capacitance between ①LMK00306's Clkout and ②LMK00306's Clkin?
The customer uses LVDS format for output.
So, should we refer to Figure.33?


<Question3>
If you have some recommendation of cascade connection with LMK00306, could you give us it?

Kind regards,

Hirotaka Matsumoto
