1.6T Ethernet PCS IP

Overview

Key Features

• The PMA service interface per lane operates with a transfer rate of 106.25Gbps per lane.
• The PCS Client Interface implements a 1600GMII conceptually identical to the 200GMII/400GMII of 802.3 Clause 119.
• The PCS implements Reed-Solomon Forward Error Correction (RS-FEC). The RS-FEC implements the RS(544,514) as defined in IEEE 802.3 using codeword interleaving.
• The RS-FEC supports external statistics collection by providing a statistics vector which provides information for codewords, corrected codewords, uncorrected codewords as well as individual symbols corrected per codeword if corrections occurred. Option to integrate RS-FEC Statistics module.
• Pseudo-random test-pattern generator and checker for transmiter and receiver testing.
• Fault detection capable of indicating faults that render a link unreliable (loss of synchronization or excessive bit errors).
• Generic host interface allowing direct access to all configuration and status registers.
• Multi-channel support with support for 4 * 400G (802.3 Clause 119) and 2 * 800G (Draft 802.3df) and 1.6T (Draft 802.3dj)
• Optional single channel 1.6T PCS.
