The ISL36111 is a settable single-channel receive-side equalizer with extended functionality for advanced protocols operating with line rates up to 11.1Gb/s such as 10G Ethernet. The ISL36111 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 design is ideal for high-density data transmission applications including active copper cable assemblies. The equalizing filter within the ISL36111 can be set to provide optimal signal fidelity for a given media and length. The compensation level for the filter is set by two external control pins. Operating on a single 1.2V power supply, the ISL36111 enables channel throughputs of 10Gb/s to 11.1Gb/s while supporting lower data rates including 8.5, 6.25, 5, 4.25, 3.125, and 2.5Gb/s. The ISL36111 uses current mode logic (CML) input/output and is packaged in a 3mm x 3mm 16 lead QFN. The device supports LOS functionality for module applications.
