LMX1214: Interfacing with LMX2582

Nandini Muralidharan

Part Number: LMX1214
Other Parts Discussed in Thread: LMX2582

Tool/software:

Hi,

I have the CLKIN_P/N pins of LMX1214 connected to RFOUT of LMX2582.

1. In that case, can you please share how to ensure the voltage compatibility between the two?

2. LMX2582 RF clockout termination (followed per datasheet) and the clock buffer side's CLKINP/N are the picture below.

Can you please review and confirm how this termination needs to be modified?

Thanks

Hi Nandini,

LMX2582 output power is configurable.

Thank you Noel for the comment.

I understand the PLL output power can be configured in TICS GUI.

What power setting from PLL output can meet the Clk buffer's clock input requirements?

Hi Nandini,

We can set the power code between 10 and 31.

Thanks - I have some more questions on this. But let me post in the PLL forum
