DisplayPort Lane Extender
QLx4270-DP
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.
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
Applications
• DisplayPort (VESA DisplayPort Standard v1.1a)
• DisplayPort adaptors and repeaters
Benefits
• Thinner gauge cable
• Extends cable reach greater than 5x
• Improved BER
