SY58030UMI-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58030UMI-TR is a high-speed, ultra-precision differential multiplexer with integrated fanout. It selects one of four differential inputs and provides two copies via a 1:2 fanout buffer. The device supports data rates up to 10.7Gbps and clock frequencies up to 7GHz. It features internal termination for AC or DC-coupled signals as low as 100mV. Outputs are 400mV LVPECL (100K temperature compensated) with rise/fall times under 80ps. Operating voltage is 2.5V ±5% or 3.3V ±10%. Propagation delay is typically 260ps. It operates from -40°C to +85°C in a 32-pin MLF package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Ultra-low jitter design with less than 10ps peak-to-peak total jitter
• Unique patented input architecture minimizes crosstalk and accepts signals down to 100mV
• Integrated 1:2 fanout buffer provides two identical copies of the selected input signal
• Internal termination allows direct interfacing with CML, LVPECL, and LVDS without external resistor networks

Signal Switches, Multiplexers, Decoders Applications

• Redundant clock and data distribution
• SONET/SDH clock and data distribution
• Loopback applications
• Fibre Channel distribution
• Gigabit Ethernet clock and data distribution

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape and reel packaging. Confirm the 'MI' suffix indicates industrial temperature range operation (-40°C to +85°C). Ensure compatibility with 2.5V or 3.3V power supplies. Check RoHS compliance status if required by specific manufacturing standards.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when low jitter and high-speed multiplexing are critical. It is suitable for systems requiring 4:1 selection with simultaneous dual output distribution. Consider alternatives like the SY58029U if 800mV LVPECL outputs are preferred over 400mV. Verify interface compatibility with source signals such as CML or LVDS.

Signal Switches, Multiplexers, Decoders Part Context

The SY58030U belongs to Micrel's Precision Edge product line, designed for high-performance timing applications. It is part of a family including the SY58028U (CML outputs) and SY58029U (800mV LVPECL outputs). The device utilizes a 32-pin MicroLeadFrame package for efficient thermal management and compact footprint.

Signal Switches, Multiplexers, Decoders Replacement Considerations

SY58029U offers similar functionality but with 800mV LVPECL outputs instead of 400mV.

Signal Switches, Multiplexers, Decoders FAQ

How does the device handle unused differential inputs?

Unused input pairs should have one end grounded through a 1kΩ resistor and the other connected to VCC through an 825Ω resistor to prevent indeterminate states.

What is the maximum operating frequency for clock signals?

The device can handle clock signals up to 7GHz, while supporting data streams up to 10.7Gbps.
