Description

The ISL36411 is a settable quad receive-side equalizer with extended functionality for advanced protocols operating with line rates up to 11.1Gbps such as InfiniBand (QDR) and 40G Ethernet (40GBase-CR4/ SR4). The ISL36411 compensates for the frequency dependent attenuation of copper twin-axial cables, extending the signal reach up to at least 10m on 28AWG cable.

The small form factor, highly-integrated quad design is ideal for high-density data transmission applications including active copper cable assemblies. The four equalizing filters within the ISL36411 can each be set to provide optimal signal fidelity for a given media and length. The compensation level for the filters is set by two external control pins.

Operating on a single 1.2V power supply, the ISL36411 enables per channel throughputs of 10Gbps to 11.1Gbps while supporting lower data rates including 8.5, 6.25, 5, 4.25, 3.125, and 2.5Gbps. The ISL36411 uses current mode logic (CML) inputs/outputs and is packaged in a 4mmx7mm 46-lead QFN. Individual lane LOS support is included for module applications.
