S28115
100Gbps Multi-Link Gearbox
The S28115 Multi-Link Gearbox PHY extends the PHY product family into virtual link aggregation and 10GBASE-R port expansion. The MLG allows up to ten independent 10GBASE-R links to be carried across a 4 x 25 Gbps interface either across a fiber-efficient 100GBASE-R4 link or to interface with a 4 x 25 Gbps next generation switch or network processor unit. Equally suited for data center switches, routers and optical modules, the S28115 benefits from superior electrical performance and enhanced diagnostic features to accelerate chip bring-up and debug at the system level. Integrated 100G mux/demux facilitates transport of up to 10 x 10GE over a 4 x 25G physical interface.
