SY55859LMG-TR

Signal Switches, Multiplexers, Decoders Overview

The SY55859LMG-TR is a dual CML 2x2 crosspoint switch optimized for high-speed data and clock applications up to 3.2 Gbps or 2.7 GHz. It operates from a +3.3V ±10% supply voltage within the industrial temperature range of –40°C to +85°C. The device features low jitter performance with 2ps RMS random jitter and 5ps peak-to-peak deterministic jitter. It utilizes a 32-pin EPAD-QFN package (5mm x 5mm) and includes internal 50Ω terminations on both inputs and outputs.
