Myriad input voltage

Hello,

what is the minimum and maximum voltage interval that i can put on the Myriad RF analog input X4 ?

I did an experiment, I adjust VGA1 gain = -4, and VGA2 gain= 25 .
at the reception, VGA2 gain = 30.

If I send a negative voltage at the reception I receive 120 mV and when I send an upper voltage than 300mV, I receive 2,24V

trips or ideas are greatly appreciated

thank you

Hello Amina,

LMS6002D analog inputs require a 0.6V common mode offset voltage with a 300 mVp-p voltage swing for
optimum performance.

Best,
Rich
