The Precise-ITC 25GPCS IP core is a cutting edge solution to the 25G/10G Ethernet application. The IP core is dual-rated for supporting 25GE (802.3by-D3.0) and 10GE (10GBASE-R). The dual-rate feature allows backward compatibility of existing 10GBASE-R application.
The 25GPCS supports 64B/66B encoding for transmission of data and control characters, optional RSFEC support at the Physical Layer. All functions of the 25GPCS are compliant with the IEEE 802.3by/D3.0.
