Display Port Sink DATASHEET QLx4270-DP FN6972 Rev 2.00 DisplayPort Lane Extender March 3, 2010 The QLx4270-DP is a settable quad receive-side Features equalizer with extended functionality for DisplayPort Supports data rates up to 2.7Gb/s per lane applications. The QLx4270-DP compensates for the frequency dependent attenuation of copper cables, Low power (78mW per channel) allowing operation on ultra-thin 40AWG cable. Low latency (<500ps) The small form factor, highly-integrated quad design is Four equalizers in a 4mmx7mm QFN package for ideal for high-density data transmission applications straight route-through architecture and simplified including active copper cable assemblies. routing Each equalizer boost is independently pin Operating on a single 1.2V power supply, the selectable and programmable QLx4270-DP enables per channel throughputs of up to 2.7Gb/s. The QLx4270-DP uses current mode logic 1.2V supply voltage (CML) inputs/outputs and is packaged in a 4mmx7mm 46 lead QFN.
