Description

The ISL35411 is a quad de-emphasis driver with extended functionality for advanced protocols operating with line rates up to 11.1 Gbps such as InfiniBand (QDR) and 40G Ethernet (40GBASE-CR4/SR4). The ISL35411 is a high-speed driver/limiting amplifier with built in
de-emphasis to drive twin-axial copper cables and compensate for the frequency dependent attenuation of PCB traces such as the SFI channel in the 10G SFP+ specification (SFF-8431).

Used in conjunction with Intersil's ISL36411 receive-side equalizer, 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. The ISL35411 uses current mode logic (CML) input/output and is packaged in a 4mmx7mm 46 lead QFN.
