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.
