Description

The ISL35111 is a de-emphasis driver with extended functionality for advanced protocols operating with line rates up to 11.1Gbps such as 10G Ethernet. The ISL35111 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 Intersils ISL36111 receive-side equalizer, ISL35111 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 ISL35111 enables channel throughputs of 10Gbps to 11.1Gbps while supporting lower data rates including 8.5, 6.25, 5, 4.25, 3.125, and 2.5Gb/s. The QL111VTx uses current mode logic (CML) input/output and is packaged in a 3mmx3mm 16 lead QFN.
