Part Number: AFE7950
Hi,
Could you check below weird spectrum?
Customer would like to use 1.5GHz interface rate on 1 Tx ch.
Center frequency is now 5GHz due to spectrum analyzer specification but they will use 9.6GHz finally.
Additional question is that AFE7950 use signed signal?
Below is latte script.
