DATASHEET QLx111GRx FN6987 Rev 0.00 11.1Gb/s Lane Extender October 26, 2009 The QLx111GRx is a settable single-channel receive- Features side equalizer with extended functionality for advanced Supports data rates up to 11.1Gb/s protocols operating with line rates up to 11.1Gb/s such as 10G Ethernet (10GBase-CR). The QLx111GRx Low power (<135mW) compensates for the frequency dependent attenuation Low latency (<500ps) of copper twin-axial cables, extending the signal reach Single channel equalizer in a 3mmx3mm QFN up to at least 10m on 28AWG cable. package for straight route-through architecture The small form factor, highly-integrated design is ideal and simplified routing for high-density data transmission applications Adjustable equalizer boost including active copper cable assemblies. The Supports 64b/66b encoded data long run lengths equalizing filter within the QLx111GRx can be set to provide optimal signal fidelity for a given media and Line silence preservation length. The compensation level for the filter is set by 1.2V supply voltage two external control pins. LOS support Operating on a single 1.2V power supply, the QLx111GRx enables per channel throughputs of Applications 10Gb/s to 11.1Gb/s while supporting lower data rates SFP+ active copper cable modules including 8.5, 6.25, 5, 4.25, 3.125, and 2.5Gb/s. The QSFP active copper cable modules QLx111GRx uses current mode logic (CML) input/output and is packaged in a 3mmx3mm 16 lead 10G Ethernet (10GBase-CR) QFN. LOS support is included for module applications.

The use of parallel 100pF and 10nF decoupling capacitors to DD ground is recommended for each of these pins for broad high-frequency noise suppression. IN P,N 2, 3 Equalizer 1 differential input, CML. The use of 100nF low ESL/ESR MLCC capacitor with at least 6GHz frequency response is recommended. CP A,B 6, 7 Control pins for setting the equalizer. CMOS logic inputs. Pins are read as a 2-digit number to set the boost level. Pins are internally pulled up and down through a 23k resistor. 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. LOS 14 LOS indicator. High output when equalized In signal is below DT threshold. Open drain output internally pulled up to V with a 10k resistor. DD DT 15 Detection Threshold. Reference DC voltage threshold for input signal power detection. Data output OUT is muted when the power of the equalized version of IN falls below the threshold. Tie to ground to disable electrical idle preservation and always enable the limiting amplifier.
