LMK05318: Figure29 and Figure30

Part Number: LMK05318

Hi all

Would you mind if we ask LMK05318?

<Question1>
On the datasheet Figure 29. Single-Ended LVCMOS to XO Input (XO_P), XO_N connects capcitance.
How much of value is recommended? 0.1uF/6.3V?
And instead of capacitance, is it(XO_N) possible to connect to GND? or pull down 10kohm?

<Question2>
On the datasheet Figure 30. Single-Ended LVCMOS (1.8, 2.5, 3.3 V) to Reference (PRIREF_P/SECREF_P), there are no descriptions about PRIREF_N and SECREF_N.
Could you let us know recommended termination for PRIREF_N and SECREF_N?
We assume that 50ohm termination is recommeded. Is it correct?

Kind regards,

Hirotaka Matsumoto

    Hi Hirotaka,

    1. XO_N can be directly tied to ground. 

    2. PRIREF_N and SECREF_N can be directly tied to ground as well.
