SY58019UMI-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58019UMI-TR is a high-speed, precision differential 2:1 multiplexer manufactured by Microchip Technology. It supports data throughput up to 10.7Gbps and clock frequencies exceeding 7GHz. The device features ultra-low jitter characteristics, including less than 1ps RMS random jitter and less than 10ps peak-to-peak deterministic jitter. It operates from a single power supply of either 2.5V ±5% or 3.3V ±10%. The component utilizes a unique input termination architecture that accepts DC-coupled and AC-coupled signals such as CML, PECL, and LVDS without external level shifting. Outputs provide a 400mV LVPECL swing with propagation delays under 240ps.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'UMI' against official documentation to confirm lead-free status and packaging details. Confirm that the MLF-16 package requires proper thermal management via the exposed pad connection. Ensure compatibility with the required 2.5V or 3.3V power supply rails before integration into the design.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when low jitter and high-speed multiplexing are critical requirements. It is suitable for interfacing various differential signal types without additional termination networks. Consider alternative models like the SY58017U if CML outputs are preferred over LVPECL. Evaluate the 16-pin MLF package constraints regarding PCB layout and thermal dissipation needs.
