Hi,

We have reviewed the AFE Page i your schematic . It looks fine . But one suggestion

You can have DNP at input which can be useful in future to debug if there is any leakage from transmit

Is it okay If we share 1 Single LDO with 2 AFEs?

Hi,

Should be ok. But LDO should be able to give the required current . Are you planning to use TGC mode or CW mode ? The required current are mentioned in datasheet and please go though it.

The highlighted nets are the INP1 and ACT1 pins and their termination capacitors so please let me know whether the distance between their routing which is 13.5 mils is fine or not?
