Ethernet 10G KR Serdes
Overview
The VHT1T28KR10 is an enhanced multi-lane 10G Ethernet Hard macro that is compatible with data transfer capabilities up to 10Gbps(10GBASEKR) and XAUI. It is designed with a standard multilane interface to the core side. It has the added advantage of not requiring an external resistor, hence saving area at the system level and a pin at the chip level.
