SY58030UMG

Signal Switches, Multiplexers, Decoders Overview

The SY58030UMG is a high-speed, ultra-precision differential multiplexer with integrated fanout buffer. It selects one of four differential inputs and provides two copies via a 1:2 fanout. The device supports data rates up to 10.7 Gbps and clock frequencies up to 7 GHz. It features 400mV LVPECL outputs with internal termination. Propagation delay ranges from 170 ps to 340 ps. Operating voltage is 2.5V ±5% or 3.3V ±10%. It operates within an industrial temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'UMG' confirms the Pb-Free NiPdAu lead finish and MLF-32 package type. Confirm the component meets RoHS compliance requirements for your assembly process. Ensure the supply voltage matches either 2.5V ±5% or 3.3V ±10% specifications before integration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when low jitter performance below 10ps peak-to-peak is required for high-speed signals. Choose this part over the SY58029U if 400mV output swing is preferred over 800mV. Consider the SY58028U if CML output compatibility is necessary instead of LVPECL.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to Micrel's Precision Edge product line, designed for high-speed digital applications. It functions as a 4:1 multiplexer combined with a 1:2 fanout buffer. The device utilizes a 32-pin MicroLeadFrame package suitable for surface mount technology in dense circuit board layouts.

Signal Switches, Multiplexers, Decoders FAQ

How does the device handle unused differential inputs?

Unused input pairs should have one end connected to ground through a 1kΩ resistor and the other left floating. Unused VT and VREF-AC pins may also be left floating.

What is the function of the VT pins on the inputs?

The VT pins provide a center-tap to the internal 50Ω termination network, allowing maximum interface flexibility for both AC-coupled and DC-coupled signals.
