TS3DDR3812: Will TS3DDR3812RUAR carry the RGMII signals without introducing any issues?

Part Number: TS3DDR3812

My customer needs to isolate RGMII signals when some circuit (CPU) is not powered up. They are using TS3DDR3812RUAR as an isolation barrier.

1. Will TS3DDR3812RUAR carry the RGMII signals without introducing any issues?
2. are there any other better IC built by TI for the job?
3. Does TI provide some buffer IC or something similar that can help drive the RGMII signals between two chips that are separated by 8 to 10inch on PCB and traversing through a set of connectors?

1. What is the maximum allowed distance (or not to exceed recommended distance) that RGMII signals can be routed in the PCB?
