SY58019UMG-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58019UMG-TR is a Precision Edge differential 2:1 multiplexer designed for high-speed signal routing. It supports data rates up to 10.7 Gbps and clock frequencies exceeding 7 GHz, with propagation delays under 240 ps. The device operates on a single supply of either 2.5 V ±5% or 3.3 V ±10%. It features an ultra-low jitter architecture, ensuring less than 1 ps RMS random jitter and less than 10 ps peak-to-peak deterministic jitter. The output provides a 400 mV LVPECL swing compatible with 100 kΩ loads.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix to confirm package type and lead finish. The 'G' suffix indicates a Pb-Free MLF-16 package with NiPdAu plating, while other suffixes may differ. Confirm moisture sensitivity levels and storage requirements before assembly. Ensure the selected variant matches the required industrial temperature range and voltage specifications for your application design.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when low jitter and high-speed multiplexing are critical. It is suitable for applications requiring interface flexibility with various differential signaling standards like CML, PECL, and LVDS. Consider alternative models if CML outputs or different output swings are needed instead of the standard 400 mV LVPECL configuration provided by this part.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to Micrel's Precision Edge product line, which focuses on high-speed, precision analog and digital signal processing solutions. The manufacturer was acquired by Microchip Technology, and current documentation reflects this transition. The device utilizes the MLF package technology for compact surface-mount integration in dense circuit board layouts.

Signal Switches, Multiplexers, Decoders Replacement Considerations

For applications requiring CML outputs, consider the SY58017U. For designs needing 800 mV LVPECL outputs, the SY58018U is the appropriate alternative. Both parts share similar form factors and operational characteristics within the same product family.
