SY58610UMG

Signal Switches, Multiplexers, Decoders Overview

The SY58610UMG is a high-speed, fully differential LVPECL 2:1 multiplexer from the Precision Edge product line. It processes clock signals up to 2.5GHz and data patterns up to 3.2Gbps with less than 10ps peak-to-peak total jitter. The device features internal termination for LVPECL, LVDS, or CML inputs as small as 100mV (200mVpp) without external level-shifting networks. It operates on a 2.5V ±5% or 3.3V ±10% supply within an industrial temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the component is sourced from authorized Microchip Technology distributors to ensure authenticity. Confirm the package marking includes the Pb-Free bar-line indicator and NiPdAu lead finish. Check RoHS compliance status against current regulatory requirements before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this part for designs requiring buffered LVPECL outputs with minimal jitter. Consider the SY58609U or SY58611U if CML or LVDS output swings are required instead. Ensure the PCB layout supports the QFN-16 exposed pad connection to ground for optimal thermal performance.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to Micrel's Precision Edge series, now manufactured by Microchip Technology. It is designed for high-performance digital communication systems where signal integrity and low latency are critical. The device integrates unique input termination to simplify interface design across various logic families.

Signal Switches, Multiplexers, Decoders Replacement Considerations

SY58609UMG provides similar functionality but with CML outputs. SY58611UMG offers LVDS outputs. Verify voltage compatibility and output swing requirements before substituting these related parts in existing designs.

Signal Switches, Multiplexers, Decoders FAQ

How does the Fail Safe Input function operate?

The FSI feature latches the output to its last valid state if the input signal amplitude drops below approximately 100mVpk, preventing metastable conditions or ringing during input failure.

What types of differential signals can the inputs accept?

The inputs accept LVPECL, LVDS, or CML differential signals, supporting both AC-coupled and DC-coupled interfaces with swings as small as 100mVpk.
