Other Parts Discussed in Thread: DS92LX1621, DS15EA101, DS15BA101

Why are the SerDes ICs DS92LX1621/22 not capable of driving 100m TP cable as the Cable Extender Chipset DS15BA101, DS15EA101?

What is the main function incorporated in the Cable Extender Chipset that makes the difference?

Is there any whitepaper covering this subject?

Hi Viktor,

The DS92LX1621/2 chipset does not include the advanced signal conditioning features as offered in the DS15BA101 and DS15EA101. In addition, the Channel-Link III interface uses full-duplex signaling; whereas the redriver/eq is more intended for point-to-point communication. For reference, please see the application notes which describe extended reach applications:
