We use 2 different version of ADL5331 in our project, but get 2 different result (Same input conditions).
Input 737MHz, -17dBm, VGA Gain = 7dB
A Chip (Datecode: 1432, 1510), Packaging factory: Amkor-Korea
ADL5331 test result: Pass
B Chip (Datecode: 1605), Packaging factory: Amkor-Philippines
ADL5331 test result: Fail
We know A chip and B chip from 2 different packaging factory (Information from PCN).
May we know what different between these two?
Thanks and Best Regards,
