SY58017UMI

Signal Switches, Multiplexers, Decoders Overview

The SY58017UMI is a high-speed, ultra-precision differential CML 2:1 multiplexer manufactured by Microchip Technology. It supports data throughput up to 10.7Gbps and clock frequencies up to 7GHz. The device features an internal 50Ω output source termination with a typical 400mV CML output swing. It operates from a 2.5V ±5% or 3.3V ±10% power supply within the industrial temperature range of –40°C to +85°C. The component utilizes a unique 3-pin input termination architecture that accepts DC-coupled and AC-coupled inputs (CML, PECL, LVDS) as small as 100mV without external level shifting or termination resistor networks.

Signal Switches, Multiplexers, Decoders Feature Summary

• Ultra-low jitter design ensuring less than 1ps RMS random jitter and less than 10ps peak-to-peak deterministic jitter for high signal integrity.
• Unique AnyGate input termination architecture allows direct interfacing with various differential signals including CML, PECL, and LVDS without additional components.
• Internal 50Ω output source termination provides fast rise/fall times guaranteed to be less than 60ps.

Signal Switches, Multiplexers, Decoders Applications

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

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the ordering suffix 'I' corresponds to the MLF-16 package with Sn-Pb lead finish in official documentation. Confirm RoHS compliance status if required, noting that Pb-Free variants use the 'G' suffix. Ensure moisture sensitivity handling protocols are followed as the device is humidity sensitive. Validate that the specific revision matches current manufacturing standards before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 2:1 multiplexer with CML outputs and internal I/O termination is required. Consider alternative models like the SY58018U or SY58019U if LVPECL output levels are necessary instead of CML. Ensure the application environment stays within the specified –40°C to +85°C operating temperature range. Verify that the input signal amplitude meets the minimum 100mV requirement for proper operation.

Signal Switches, Multiplexers, Decoders Part Context

The SY58017UMI belongs to Micrel’s Precision Edge product line, now part of Microchip Technology's portfolio. It is designed for high-speed digital applications requiring precise timing and low jitter performance. The device is housed in a 16-pin MLF package, offering a compact solution for dense circuit board layouts while maintaining thermal efficiency through its exposed pad design.

Signal Switches, Multiplexers, Decoders Replacement Considerations

For LVPECL output requirements, consider the SY58018U or SY58019U Multiplexers. For dual-channel configurations, evaluate the SY58025U or SY58026U devices. Direct pin-compatible replacements within the same family should be verified against specific electrical characteristics and package dimensions.
