Hello:
I am using the AFE5808 in my ultrasonic system design, but now we are facing a problem: we can't get the ADC data from the LVDS outputs. I connect a sine signal of 600mVpp to the AFE, but the LVDS output has no change. In order to test our data receive program, We used the TEST_PATTERN_MODE(set reg 0x02[15:13] = 011), and we get the right data we write to AFE5808, and we can also read the command we write to the registers rightly, which means our configuration program and the digital part is right.
My register configuration is that : reg 01 0x8000; reg 03 0x6000; reg 04 0x0002, the rest registers are all set to 0;
Could any one who can tell me what's wrong with my design? I'll be very thankful!
