ISL35111 FN6975
Rev 2.00
Jul 12, 2012 11.1Gb/s Driver
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). Features Used in conjunction with Intersil’s ISL36111 receive-side
equalizer, ISL35111 enables active copper cable assemblies
that support 10G serial data transmission over >15m of
twin-axial copper cables. Single channel driver in a 3mmx3mm QFN package for
straight route-through architecture and simplified routing 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,
2.5 and 1Gb/s. The ISL35111 uses current mode logic (CML)
input/output and is packaged in a 3mmx3mm 16 lead QFN. 1.2V supply voltage Supports data rates up to 11.1Gbps Low power (85mW typical) Low latency (<500ps) Adjustable output de-emphasis Supports 64b/66b encoded data – long run lengths Line silence preservation TX_Disable and TX_LOS Applications Active copper cable modules (SFP+, QSFP, CXP, etc.) Optical transceiver modules (SFP+, QSFP, CXP, etc.) 10G Ethernet 40G/100G Ethernet Fibre Channel High-speed active cable assemblies High-speed printed circuit board (PCB) traces Benefits Thinner gauge cable Extends cable reach greater than 3x Improved BER 1.2V LOS
