CDCE72010EVM: Phase Noise

Part Number: CDCE72010EVM

Hi TI team,

We need your help to check our customer concerns regarding the improvement of phase noise.

On the CDCE72010EVM, output 1 and output 8 have a footprint option for installing crystal filters that can drive the phase noise floor down by 10 dB or 15 db. As a source to provide a clean signal at 491.52MHz

1. What is the part used to justify that an improvement of 10~15dB?

2. With regards to footprint, what is the recommended crystal filter that can be used?

Thank you in advance for the response.


Kind regards,

 

Jonathan
