SY58038UMI

Signal Switches, Multiplexers, Decoders Overview

The SY58038UMI is an ultra-precision, high-speed 8:1 multiplexer with a 1:2 differential fanout buffer. It distributes clock frequencies from DC to 3.5GHz and supports data rates up to 4.5Gbps. The device features low jitter (72fsrms typical) and low skew (<15ps output-to-output). It operates on a 2.5V ±5% or 3.3V ±10% supply within the -40°C to +85°C industrial temperature range. The component utilizes a unique 3-pin input termination architecture for direct interfacing with CML, PECL, or LVDS signals as small as 100mV without external level shifting.
