SY58609UMG

Signal Switches, Multiplexers, Decoders Overview

The SY58609UMG is a high-speed, fully differential CML 2:1 multiplexer from the Precision Edge product line. It processes clock signals up to 2.5GHz and data patterns up to 4.25Gbps with less than 20ps skew and under 10ps peak-to-peak total jitter. The device features internal termination for LVPECL, LVDS, or CML inputs as small as 100mV without external components. 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 specific part number matches the required package type and lead finish specifications. Confirm operational voltage requirements align with the 2.5V or 3.3V supply options. Ensure environmental ratings meet the industrial temperature range needs. Cross-reference datasheet revisions to confirm compatibility with existing designs.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when low jitter and high-speed data routing are critical. Consider alternative models like the SY58610U or SY58611U if LVPECL or LVDS outputs are required instead of CML. Evaluate input signal amplitudes to ensure they fall within the supported range for optimal performance.
