Part Number:AFE5808A
Dear TI Experts
I am using 16pcs AFE5808A for 128channels projects and meet with a problem really needs your suggestion:
Channels of CH40 ~ CH47（total 8 channels） could not collect signals (all noise) in receiving channel test.These eight channels come from the same AFE5808A
After test this AFE5808A， In INP1~INP8, we can observe the 2 MHz sinusoidal wave signal injected, but in PGA Test Mode CW_IP_AMPINM/P and CW_QP_AMPINM/P PIN, we can not see the amplified sinusoidal wave signal
In contrast, other AFE5808a has sinusoidal wave signal at the same location!
Do you have any suggestions? I can send you shematic by email if you need this~
