Quad Driver

ISL35411

Features

• Supports four channels with data rates up to

11.1Gbps

The ISL35411 is a quad de-emphasis driver with

extended functionality for advanced protocols operating

with line rates up to 11.1 Gbps such as InfiniBand (QDR)

and 40G Ethernet (40GBASE-CR4/SR4). The ISL35411

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).

• Low power (90mW per channel)

• Low latency

• Adjustable output de-emphasis

• Four drivers in a 4mmx7mm QFN package for

straight route-through architecture & simplified

routing

• Supports 64b/66b encoded data – long run lengths

• Line silence preservation

• 1.2V supply voltage

Used in conjunction with Intersil’s ISL36411 receive-side

equalizer, ISL35411 enables active copper cable

assemblies that support 10G serial data transmission

over >15m of twin-axial copper cables.

• TX_Disable

Operating on a single 1.2V power supply, the ISL35411

enables per channel throughputs of 10Gbps to 11.1Gbps.

The ISL35411 uses current mode logic (CML)

input/output and is packaged in a 4mmx7mm 46 lead

QFN.

Applications

• QSFP active copper cable modules

• InfiniBand (QDR)

• 40G Ethernet (40GBase-CR4/SR4)

• 100G Ethernet (100GBase-CR10/SR10)

• High-speed active cable assemblies

• High-speed printed circuit board (PCB) traces

Benefits

• Thinner gauge cable

• Extends cable reach greater than 3x

• Improved BER
