SY58028UMG

Signal Switches, Multiplexers, Decoders Overview

The SY58028UMG is a high-speed, precision differential CML multiplexer manufactured by Microchip Technology. It selects one of four differential inputs and provides two copies via an integrated 1:2 fanout buffer. The device supports data rates up to 10.7 Gbps and clock frequencies up to 7 GHz. It operates from a single 2.5V ±5% or 3.3V ±10% power supply within the industrial temperature range of –40°C to +85°C. The component features internal I/O termination, accepts input signals as low as 100mV, and utilizes a 32-pin MLF package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Loopback configurations
• Fibre Channel distribution
• Gigabit Ethernet clock and data distribution

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix to confirm the package type and lead finish. The 'UMG' designation indicates a Pb-Free MLF-32 package with NiPdAu finish. Confirm whether the required quantity needs the tape and reel variant (ending in TR) or the tube packaging. Ensure compatibility with the intended power supply voltage of either 2.5V or 3.3V during the procurement phase.

Signal Switches, Multiplexers, Decoders Selection Notes

Choose this component when a 4-to-1 multiplexing function with simultaneous dual-output buffering is required. It is suitable for applications demanding high-speed signal integrity with minimal jitter. Consider alternative models like the SY58029U if LVPECL output levels are preferred over CML. Verify that the system can accommodate the 32-pin MLF package dimensions and thermal requirements.
