QLX4270RIQSR

Specialized Overview

The QLX4270RIQSR is a quad receive-side equalizer designed for DisplayPort applications, manufactured by Renesas Electronics Corporation. It operates on a single 1.2V supply voltage and supports per-channel throughputs of up to 2.7Gb/s. The device utilizes current mode logic (CML) inputs and outputs to compensate for frequency-dependent attenuation in copper cables. It is housed in a compact 4mm x 7mm 46-lead QFN package.
