1. Description

LT87101UX is a dual-port redriver with signal conditioning suitable for DP2.1 applications with data rates up to 10 Gbps. The continuous time linear equalizer (CTLE) of the receiver provides adjustable boost to compensate up to 27 dB insertion-loss at 5 GHz. The transmitter features a programmable amplitude voltage level up to 1200 mVpp and de-emphasis up to 8 dB.   
In order to save power consumption, LT87101UX can work well from 1.8V to 2.5V power supply in external LDO mode.
LT87101UX is fabricated in advanced CMOS process and implemented in 10mm x 5.5mm QFN54 package.
