SY58611UMG-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58611UMG-TR is a high-speed, fully differential LVDS 2:1 multiplexer from the Precision Edge® family. It processes clocks up to 2.5GHz and data rates up to 3.2Gbps with less than 20ps of skew and under 10pspp total jitter. The device operates on a 2.5V ±5% supply within an industrial temperature range of –40°C to +85°C. It features patented internal termination accepting CML, LVPECL, or LVDS inputs via DC- or AC-coupled interfaces. The output provides a buffered LVDS signal with guaranteed rise/fall times under 120ps.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the component matches the original Micrel specification before integration. Confirm the package marking includes the Pb-Free bar-line indicator and NiPdAu lead finish. Ensure the operating environment remains within the specified industrial temperature limits and power supply tolerances.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this part for applications requiring low jitter and fail-safe operation in LVDS environments. Consider the SY58609U or SY58610U if CML or LVPECL outputs are required instead of LVDS. Verify that the single-ended TTL/CMOS-compatible SEL input threshold aligns with the system logic levels.

Signal Switches, Multiplexers, Decoders FAQ

How does the Fail-Safe Input function operate?

The circuit senses the input signal amplitude and latches the output to its last valid state if the signal drops below approximately 30mVPK, preventing metastability.

What input signal swings are supported?

The device accepts AC- or DC-coupled differential signals as small as 100mVPK (200mV pp) directly from CML, PECL, or LVDS sources.
