SY58027UMG

Signal Switches, Multiplexers, Decoders Overview

The SY58027UMG is a Precision Edge dual 2:1 multiplexer featuring two independent differential muxes with guaranteed AC performance over temperature and voltage. It supports data rates up to 10.7 Gbps with propagation delays under 290ps and rise/fall times below 80ps. The device incorporates unique input isolation to minimize crosstalk and ultra-low jitter characteristics, including less than 1ps RMS random jitter. It accepts DC-coupled and AC-coupled inputs via a VT pin for CML, LVDS, and PECL standards. Outputs provide 400mV LVPECL swing. Operating from a single 2.5V or 3.3V supply, it functions within an industrial temperature range of -40°C to +85°C in a 32-pin MLF package.
