Hello experts,
I got some question about SGMII design from customer.
Could you give me advice?
1. Are these capacitors (C5,C6) for AC coupling (User guide P14)?
2. From public "Serial-GMII Specification", receive input voltage range is 675mV-1725mV.
They think is it difficult to meet receive input voltage range, if there are AC coupling capacitors.
Is it correct?
I'm not familiar with high speed signal line, so I would appreciate if you would give me advice.
Thanks and best regards,
Ryo Akashi
