SY58030UMI

Signal Switches, Multiplexers, Decoders Overview

The SY58030UMI is a high-speed, precision differential multiplexer manufactured by Microchip Technology in the MLF-32 package. It operates within an industrial temperature range of -40°C to +85°C and supports power supplies of 2.5V ±5% or 3.3V ±10%. The device functions as a 4:1 multiplexer with an integrated 1:2 fanout buffer, providing two copies of the selected input signal. It handles data rates up to 10.7Gbps and clock frequencies up to 7GHz. Key electrical parameters include a propagation delay of less than 340ps from input to output, rise/fall times under 80ps, and a typical output voltage swing of 400mV.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates a 4:1 differential multiplexer with an internal 1:2 fanout buffer for simultaneous dual-output distribution.
• Features unique patented input termination architecture that accepts AC-coupled and DC-coupled signals without external level shifting.
• Delivers ultra-low jitter performance with guaranteed deterministic and random jitter specifications across operating conditions.
• Provides internally temperature-compensated LVPECL outputs with fast rise and fall times.

Signal Switches, Multiplexers, Decoders Applications

• Redundant clock and data distribution systems
• SONET/SDH clock and data distribution networks
• Loopback testing configurations
• Fibre Channel distribution architectures
• Gigabit Ethernet clock and data distribution

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the ordering suffix 'I' confirms the MLF-32 package and industrial temperature range (-40°C to +85°C). Confirm lead finish specifications if RoHS compliance is required, as standard versions may differ from Pb-Free variants. Ensure supply voltage requirements match the specific system design (2.5V or 3.3V) before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a low-jitter 4:1 multiplexer with dual outputs is required for high-speed serial links. It is suitable for interfacing with CML, LVPECL, or LVDS sources due to its flexible input termination. Consider alternative models like the SY58029U if higher output swings are needed, or the SY58028U if CML outputs are preferred over LVPECL.

Signal Switches, Multiplexers, Decoders Part Context

The SY58030UMI belongs to Micrel's Precision Edge product line, now distributed by Microchip Technology. This series focuses on ultra-high-speed logic devices designed for demanding telecommunications and networking applications. The part utilizes a 32-pin MicroLeadFrame package optimized for thermal management and high-density PCB layouts.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The SY58030UMG serves as a direct replacement offering Pb-free construction with identical electrical characteristics. For applications requiring different output swings, the SY58029U provides 800mV LVPECL outputs, while the SY58028U offers CML outputs.
