DATASHEET QLx4300-S45 FN6982 Rev 1.00 Quad Lane Extender November 19, 2009 The QLx4300-S45 is a settable quad receive-side Features equalizer with extended functionality for advanced Supports data rates up to 3.125Gb/s protocols operating with line rates up to 3.125Gb/s Low power (78mW per channel) such as InfiniBand (SDR) and 10GBase-CX4. The QLx4300-S45 compensates for the frequency Low latency (<500ps) dependent attenuation of copper twin-axial cables, Four equalizers in a 4mmx7mm QFN package for extending the signal reach up to 40m on 24AWG cable. straight route-through architecture and simplified routing The small form factor, highly-integrated quad design is ideal for high-density data transmission applications Each equalizer boost is independently pin including active copper cable assemblies. The four selectable and programmable equalizing filters within the QLx4300-S45 can each be Beacon signal support and line silence preservation set to one of 32 compensation levels, providing optimal signal fidelity for a given media and length. The 1.2V supply voltage compensation level for each filter can be set by either Individual channel power-down (impedance select) (a) three external control pins or (b) a serial bus interface. When the external control pins are used, 18 Applications of the 32 boost levels are available for each channel. If the serial bus is used, all 32 compensation levels are InfiniBand (SDR) available. 10GBase-CX4 Operating on a single 1.2V power supply, the PCI Express (Gen 1) QLx4300-S45 enables per channel throughputs of up DisplayPort to 3.125Gb/s while supporting the lower data rates of XAUI 2.5Gb/s and 1.5Gb/s. The QLx4300-S45 uses current mode logic (CML) inputs/outputs and is packaged in a SAS (1.0) 4mmx7mm 46 lead QFN. Individual lane impedance High-speed active cable assemblies select support is included for module applications.
