MAX4927 is a high-performance, low-power, 4-pair bidirectional switch that meets the needs of Gigabit Ethernet (10/100/1000) Base-T switching as well as LVDS and LVPECL switching.
The MAX4927 is a high‑speed analog switch designed for 1000 Base‑T Ethernet, LVDS, LVPECL and other low‑voltage differential signals. It offers up to +15 kV ESD protection, ultra‑low on‑resistance and capacitance, and built‑in LED switches for docking‑station applications.
The device is supplied in a space‑saving 56‑pin TQFN package (5 mm × 11 mm) and operates from –40 °C to +85 °C. Detailed electrical characteristics, pin descriptions, and layout recommendations are provided for designers.
