SY58017UMI-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58017UMI-TR is a high-speed, differential 2:1 multiplexer from Microchip Technology's Precision Edge line. It supports data rates up to 10.7Gbps and clock frequencies up to 7GHz. The device features an AnyGate input architecture accepting CML, PECL, or LVDS signals with internal 50Ω termination. Outputs are source-terminated CML with typical 400mV swing. Operating voltage ranges from 2.375V to 3.6V across the -40°C to +85°C industrial temperature range.

Signal Switches, Multiplexers, Decoders Feature Summary

• AnyGate input interface supporting AC-coupled and DC-coupled differential signals without external level shifting
• Internal 50Ω output source termination for simplified board layout
• Ultra-low jitter design ensuring signal integrity in high-speed applications

Signal Switches, Multiplexers, Decoders Applications

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

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering suffix 'UMI' corresponds to the MLF-16 package with Sn-Pb lead finish as documented in the official datasheet. Confirm that the 'TR' suffix indicates tape and reel packaging. Ensure procurement specifications match the Pb-free alternative (SY58017UMG) if RoHS compliance is required for the target assembly process.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when interfacing mixed signal standards such as CML, PECL, or LVDS into a single CML output path. The internal termination eliminates the need for external resistors at the inputs. Consider the SY58018U or SY58019U if LVPECL outputs are required instead of CML. Verify power supply stability within the specified 2.5V ±5% or 3.3V ±10% range.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to Micrel's Precision Edge family of ultra-high-speed logic devices, now manufactured by Microchip Technology following acquisition. The SY58017U series focuses on low-jitter multiplexing for telecommunications and networking infrastructure. It complements other devices like the SY58025U dual mux and SY58016L line driver within the same product ecosystem.

Signal Switches, Multiplexers, Decoders Replacement Considerations

For Pb-free requirements, use SY58017UMG or SY58017UMG-TR. For LVPECL output variants, consider SY58018U or SY58019U.
