Other Parts Discussed in Thread: AFE5809
Hello,
I need some help regarding AFE5809EVM.
First, we used internal test pattern generation to generate Ramp signal and then we decoded the lvds output. Figure 1. is the output for Ramp test pattern. Note: We are using onboard clock which is 40MHz. Demodulator is bypassed.
Now, we selected test pattern to None and then feed the live signal which is Sine wave of 1MHz from a generator. everything is same no change. Here is the output we got:
From image we can see the our data is saturating. We are using 300mVpp input signal amplitude. which is acceptable range of afe input signal amplitude.
My questions:
1. Can you please suggest us, how we can get eliminate the saturation? so we can see the clear sine wave?
2. we want to use 400KHz to 500KHz signal, do we have to change any input capacitors for that frequency?
If you have any questions please just ask! Appreciate your help!
Thank you.
