DATASHEET ISL36111 FN6974 Rev 2.00 11.1Gb/s Lane Extender Jul 12, 2012 The ISL36111 is a settable single-channel receive-side Features equalizer with extended functionality for advanced protocols Supports data rates up to 11.1Gb/s operating with line rates up to 11.1Gb/s, such as 10G Ethernet. The ISL36111 compensates for the frequency Low power (~110mW) dependent attenuation of copper twin-axial cables, extending Low latency (<500ps) the signal reach up to at least 10m on 28AWG cable. Single channel equalizer in a 3mmx3mm QFN package for The small form factor, highly-integrated design is ideal for straight route-through architecture and simplified routing high-density data transmission applications including active Adjustable equalizer boost copper cable assemblies. The equalizing filter within the ISL36111 can be set to provide optimal signal fidelity for a Supports 64b/66b encoded data long run lengths given media and length. The compensation level for the filter is Line silence preservation set by two external control pins. 1.2V supply voltage Operating on a single 1.2V power supply, the ISL36111 Loss of Signal support enables channel throughputs of 10Gb/s to 11.1Gb/s while supporting lower data rates including 8.5, 6.25, 5, 4.25, 3.125, Applications 2.5 and 1 Gb/s. The ISL36111 uses current mode logic (CML) input/output and is packaged in a 3mmx3mm 16 lead QFN. SFP+ active copper cable modules The device supports LOS functionality for module applications.

The use of parallel 100pF and 47nF decoupling capacitors to ground is DD recommended for each of these pins for broad high-frequency noise suppression. IN P,N 2, 3 Equalizer differential input, CML. The use of 100nF low ESL/ESR MLCC capacitor with at least 6GHz frequency response is recommended. LOSB 4 LOS BAR indicator. Low output when input signal is below DT threshold. This pin is internally pulled HIGH with an 11k resistor. CP A,B 6, 7 Control pins for setting equalizer boost level. Tri-state inputs. Pins are read as a 2-digit number to set the boost level. A is the MSB, and B is the LSB. GND 5, 8, 13, 16 These pins must be grounded. OUT P,N 11, 10 Equalizer differential output, CML. The use of 100nF low ESL/ESR MLCC capacitor with at least 6GHz frequency response is recommended. DT 15 Detection Threshold. Reference DC voltage threshold for input signal power detection. Data output OUT P,N is muted when the power of the input signal IN P,N falls below the threshold. Tie to ground to disable electrical idle preservation and always enable the output driver. Exposed Pad - Exposed pad. For proper electrical and thermal performance, this pad should be connected to the PCB ground plane. FN6974 Rev 2.00 Page 2 of 9 Jul 12, 2012 GND GND DT CPA NC CPB GND GND
