QLX4270-DP: 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.

Operating on a single 1.2V power supply, the QLx4270-DP enables per channel throughputs of up to 2.7Gb/s. The QLx4270-DP uses current mode logic (CML) inputs/outputs and is packaged in a 4mmx7mm 46 lead QFN.

Key Features
  • Supports data rates up to 2.7Gb/s per lane
  • Low power (78mW per channel)
  • Low latency (<500ps)
  • Four equalizers in a 4mmx7mm QFN package for straight route-through architecture and simplified routing
  • Each equalizer boost is independently pin selectable and programmable
  • 1.2V supply voltage Benefits
  • Thinner gauge cable
  • Extends cable reach greater than 5x
  • Improved BER
Applications
  • DisplayPort (VESA DisplayPort Standard v1.1a)
  • DisplayPort adaptors and repeaters
