["Lee Ritchey" <leeritchey@xxxxxxxxxxxxx>]

Zhangkun,

If  you have designed your power subsystem correctly, the Vcc and ground
planes of you power supply will be tied to each other through less than 10
milliohms at all of the frequencies that are in you signal, so you don't
haveto worry about a disconnect.

The driver and receiver use GND as their reference. The trace use VCC as
its reference plane. As shown in power integrity, there is impedance
between power and ground. Therefore, there are one disconnection at the
driver and one disconnection at the receiver. Would these two disconnection
disgrade signal integrity?
