Other Parts Discussed in Thread: LMK61E2EVM, LMK61E2
Hi there,
I've noticed that the phase noise of the LMK61E07 is not as good as it was when I2C operations taken place.
I've tried periodically sending commands to change the LMK61E07 frequency or sending command just to read the product ID, or sending non-I2C PRN data to the I2C ports on the chip.
All the above three significantly worsen the phase noise of the LMK61E07 at the sideband related to the I2C port's communication.
Please see the following figure attached.
Thanks.
Regards,
Wade
