The ISL35411 is a quad de-emphasis driver with extended functionality for advanced protocols operating with line rates up to 11. 1Gbps. It integrates a high-speed driver/limiting amplifier with built-in de-emphasis to compensate for the frequency dependent attenuation of PCB traces and twin-axial copper cables. Supported protocols include 4k/8k video capable DisplayPort v1. 3 (HBR1/2/3), InfiniBand (QDR), 40G Ethernet (40GBASECR4/SR4) and 10G SFP+ specification (SFF-8431). Used in conjunction with Intersil's ISL36411 receive-side equalizer, the ISL35411 enables active copper cable assemblies that support 10G serial data transmission over >15m of twin-axial copper cables. Operating on a single 1. 2V power supply, the ISL35411 enables per channel throughputs of 10Gbps to 11. 1Gbps. High data rates are achieved by using Current Mode Logic (CML) inputs and outputs and is packaged in a 4mmx7mm 46 Ld QFN.
