Description
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 the device is packaged in a 4mm x 7mm 46 Ld QFN. Individual lane LOS support is included for module applications.
