LMX2820EVM: Internal Reference Oscillator Y1

Hi sb,

The phase noise of the reference clock should match with your system requirement. You can use PLL Sim to estimate the phase noise contribution from the reference clock.

We do recommend to use a higher frequency reference clock. This will allow us to use a higher fpd and as a result, reduce PLL noise.

Thank you for your reply Noel Fung---and for writing the LMX2820EVM Evaluation Module User Guide!

My question is, what type of crystal can be soldered in Y1 pads of the Evaluation Module PCB---as illustrated in the bottom-right cell in Table A-1 of the User Guide (highlighted in pink below)? An example of manufacturer and part number would be great.
