2-port 100GbE/40GbE/10GbE QSFP28 Signal Conditioner Reference Design (TIDA-00427)

This verified reference design is a signal conditioning solution for front-port QSFP28 supporting two 100GbE ports compatible with 100G-CR4/SR4/LR4, 40G-CR4/SR4/LR4 and 10G SFF-8431 requirements. The design is applicable to optical and passive/active copper cables. It allows for reach extension between the Switch ASIC and the front-port QSFP28 which is often required for the outermost ports of a Top-of-Rack (ToR) switch or for add-in mezzanine implementations of QSFP28 line cards. This reference design offers the flexibility for users to upgrade from a DS280BR810 Repeater to the pin-compatible DS250DF810 Retimer.


Front-port stacked QSFP28 implementation with signal conditioning to support 100GbE/40GbE/10GbE optical and passive copper Extends reach between Switch and front-port by up to 3x beyond CAUI-4 host channel loss limit Low-power/low-cost solution for front-port signal conditioning Applicable to Top-of-Rack (ToR) switch and line card systems Single power supply, no firmware required, no heatsink required, no reference clock required Lab-tested HW example including 100GbE/40GbE/10GbE-specific test data
