ISL36411

Quad Lane Extender ISL36411 The ISL36411 is a settable quad receive-side equalizer with extended functionality for advanced protocols operating with line rates up to 11.1Gbps such as InfiniBand (QDR) and 40G Ethernet (40GBase-CR4/ SR4). The ISL36411 compensates for the frequency dependent attenuation of copper twin-axial cables, extending the signal reach up to at least 10m on 28AWG cable. 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 10Gbps to 11.1Gbps while supporting lower data rates including 8.5, 6.25, 5, 4.25, 3.125, and 2.5Gbps. The ISL36411 uses current mode logic (CML) inputs/outputs and is packaged in a 4mmx7mm 46-lead QFN. Individual lane LOS support is included for module applications. ISL36411 Features • Supports four channels with data rates up to 11.1Gbps • Low power (~110mW per channel) • Low latency (6GHz bandwidth) 100pF* NC ISL36411 LANE EXTENDER Bypass circuit for each VDD pin (*100pF capacitor should be positioned closest to the pin) NOTES: 15. See “Control Pin Boost Setting” on page 7 for information on how to connect the CP pins. 16. See “Detection Thereshold (DT) Pin Functionality” on page 8 for details on DT pin operation. FIGURE 6.

To address this, Intersil has developed its groundbreaking Q:ACTIVE® product line. By integrating its analog ICs inside cabling interconnects, Intersil is able to achieve unsurpassed improvements in reach, power consumption, latency, and cable gauge size as well as increased airflow in tomorrow’s datacenters. This new technology transforms passive cabling into intelligent “roadways” that yield lower operating expenses and capital expenditures for the expanding datacenter. Intersil Lane Extenders allow greater reach over existing cabling while reducing the need for thicker cables. This significantly reduces cable weight and clutter, increases airflow, and improves power consumption. 10 FN6965.1 March 25, 2010 ISL36411 Revision History The revision history provided is for informational purposes only and is believed to be accurate, but not warranted.
