SY58024UMI

Signal Switches, Multiplexers, Decoders Overview

The SY58024UMI is a dual 2x2 CML crosspoint switch manufactured by Microchip Technology (formerly Micrel). It supports data rates up to 10.7 Gbps and clock frequencies of 6 GHz. The device operates on a single supply voltage of 2.5V ±5% or 3.3V ±10%. Key electrical parameters include propagation delay of less than 350ps, channel-to-channel skew under 20ps, and total jitter below 10ps peak-to-peak. It features internal I/O termination for LVPECL, LVDS, and CML inputs and is housed in a 32-pin MLF package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual 2x2 architecture providing two identical output copies with ultra-low jitter
• Unique patent-pending input termination allows direct interface to LVPECL, LVDS, and CML signals without external level-shifting
• Fully differential inputs and outputs with guaranteed AC performance over temperature and voltage
• Internal 50Ω source termination on CML outputs

Signal Switches, Multiplexers, Decoders Applications

• Gigabit Ethernet data and clock routing
• SONET data and clocking routing
• Switch fabric clock routing
• Redundant switchover systems
• Backplane redundancy

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the ordering suffix 'MI' corresponds to the MLF-32 package with Sn-Pb lead finish as specified in the datasheet. Confirm that the Pb-Free variant requires the 'MG' suffix. Ensure compatibility with industrial temperature ranges (-40°C to +85°C) and check moisture sensitivity levels before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring high-speed signal routing with minimal skew. Compare against the SY58023U if only a single 2x2 switch is needed. Ensure power supply stability within the 2.5V or 3.3V specifications to maintain the guaranteed jitter performance. Verify PCB layout capabilities for the exposed pad thermal management requirements of the MLF package.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to Micrel's Precision Edge product line, designed for high-speed communication interfaces. It is functionally similar to the SY58023U but provides dual independent switches instead of a single unit. The device is categorized under Analog & Digital Crosspoint ICs within the Communication & Networking ICs subcategory.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The SY58023U serves as a functional substitute for single-channel applications. For Pb-free requirements, the SY58024UMG is the equivalent alternative. Verify pinout and electrical characteristics match when substituting.
