SY58038UMI-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58038UMI-TR is an ultra-precision, high-speed 8:1 multiplexer with a 1:2 LVPECL fanout buffer. It operates from a 2.5V ±5% or 3.3V ±10% supply and supports DC to 4.5Gbps data rates. The device features internal termination for AC- or DC-coupled inputs as small as 100mV without external networks. It provides two low-skew LVPECL outputs with less than 100ps rise/fall times. RMS phase jitter is typically 72fsrms at 622MHz. It is housed in a 44-pin QFN package.
