DisplayPort Lane Extender

The QLx4270-DP is a settable quad receive-side equalizer with extended functionality for DisplayPort applications. The QLx4270-DP compensates for the frequency dependent attenuation of copper cables, allowing operation on ultra-thin 40AWG cable.

The small form factor, highly-integrated quad design is ideal for high-density data transmission applications including active copper cable assemblies.
