Part Number: AFE4404
Other Parts Discussed in Thread: AFE4400

Hi,

I can't seem to find a reference design for the AFE4404. I am hoping to find an example PCB layout to follow. Can anyone help?

Thanks.

Hi Prabin,

This reference design is based on the AFE4400 which has a VQFN footprint. The AFE4404 has a DSBGA footprint.

There is not much details in the AFE4404 datasheet on layout and routing guidelines.

Hi Kian,

Even though above mentioned link is for AFE4400, the guidelines will be same.
You can look for routing of the input pins ( should be differential pair). Trace width of TX pins should be thicker to carry high current.
Avoid any high frequency switching signal near the input pins to reduce the interference..
