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. Features The small form factor, highly-integrated quad design is
ideal for high-density data transmission applications
including active copper cable assemblies. Four equalizers in a 4mmx7mm QFN package for
straight route-through architecture and simplified
routing 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. Each equalizer boost is independently pin
selectable and programmable Supports data rates up to 2.7Gb/s per lane Low power (78mW per channel) Low latency (<500ps) 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 Typical Application Circuit
