Microchip Technology, Inc. Integrated Circuits (ICs) - Logic - Signal Switches, Multiplexers, Decoders SY55858UHC

The SY55858U is a high-speed dual 2x2 crosspoint switch designed for low-voltage applications, supporting a maximum frequency of over 3.0 GHz and data rates up to 3 Gbps. It features a non-blocking architecture, allowing any input to connect to any output, making it suitable for applications such as SONET/SDH optical transport and backplane redundancy. This device operates with a supply voltage range of 2.3V to 3.6V and is compatible with TTL/CMOS control logic. It has fully differential inputs and outputs, with 50,Ѷ compatible outputs for CML signals. The unique input termination design allows for easy interfacing with both AC-coupled and DC-coupled signals, accommodating various logic standards. The SY55858U is housed in a 32-pin EPAD-TQFP package and is rated for an operating temperature range of -40¬8C to +85¬8C. Its flexibility in configuration allows it to function as a dual 2:1 multiplexer, dual 1:2 fanout buffer, or quad buffer, making it a versatile choice for engineers looking for reliable signal switching solutions.
