Part Number: LMX2571

Can Ti provide a spur test result for the condition that:

1.Use internal VCO for RX and TX

2.Clock freq:26MHz

3.phase detector freq :130MHz

4.TX freq:350～400MHz

5.RX freq:700～800MHz

Hello,

The spurious performance is specific to the exact frequencies used, but in general you can expect most spurs to be < - 75 dBc with proper loop filter design.

You can find some typical plots of phase noise and spurious in the datasheet and the EVM user guide.
