SY58019UMI

Signal Switches, Multiplexers, Decoders Overview

The SY58019UMI is a high-speed, precision differential 2:1 multiplexer from the Precision Edge product line. 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 on a 2.5V ±5% or 3.3V ±10% power supply within an industrial temperature range of -40°C to +85°C. Outputs provide a 400mV LVPECL swing with propagation delays under 240ps.

Signal Switches, Multiplexers, Decoders Feature Summary

• Features unique input termination architecture accepting AC- or DC-coupled signals as small as 100mV without external level shifting or termination networks.
• Delivers ultra-low crosstalk-induced jitter for high-fidelity signal integrity in demanding applications.
• Provides 400mV LVPECL outputs compatible with 100k loads and extremely fast rise/fall times.

Signal Switches, Multiplexers, Decoders Applications

• Redundant clock distribution
• OC-3 to OC-192 SONET/SDH clock and data distribution
• Loopback configurations
• Fibre Channel distribution

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific ordering suffix matches the required lead finish and packaging format. The 'I' suffix indicates the Industrial operating temperature range. Confirm whether tape and reel packaging is needed, as this requires a separate 'TR' suffix designation distinct from the standard tray configuration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when interfacing with various differential standards such as CML, PECL, or LVDS due to its flexible input termination. Choose this part over the SY58017U if LVPECL outputs are required instead of CML. Ensure the design accommodates the 400mV output swing and utilizes appropriate termination networks at the load side.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to Micrel's Precision Edge family of high-speed logic components. It serves as a core switching element for routing differential signals in telecommunications and networking infrastructure. The MLF-16 package provides thermal efficiency suitable for dense PCB layouts requiring robust heat dissipation through the exposed pad.

Signal Switches, Multiplexers, Decoders Replacement Considerations

For CML output requirements, consider the SY58017U. For applications necessitating 800mV LVPECL outputs, the SY58018U is the designated alternative within the same product family.
