ISL36411

Quad Lane Extender

OVERVIEW

The ISL36411 is a quad receive-side equalizer with extended functionality for advanced protocols operating with line rates up to 11.1Gbps. It integrates a driver/limiting amplifier with a programmable equalizer to compensate for the frequency dependent attenuation of PCB traces and twin-axial cables. The ISL36411 is capable of extending signal reach up to 10m on 28AWG cable. Supported protocols include 4k/8k video capable DisplayPort v1.3 (HBR1/2/3), USB 3.1 Gen 2 at 10Gbps. InfiniBand (QDR), 40G Ethernet (40GBASECR4/SR4), and 10G SFP+ specification (SFF-8431).

The small form factor, highly-integrated quad design is ideal for high-density data transmission applications including active copper cable assemblies. The four equalizing filters within the ISL36411 can each be set to provide optimal signal fidelity for a given media and length. The compensation level for the filters is set by two external control pins.

Operating on a single 1.2V power supply, the ISL36411 enables per channel throughputs of up to 11.1Gbps while passing USB3.x LFPS signals as low as 100kHz. High data rates are achieved by using Current Mode Logic (CML) inputs and outputs and is packaged in a 4mmx7mm 46 Ld QFN. Individual lane LOS support is included for module applications.
