SY58019UMG

Signal Switches, Multiplexers, Decoders Overview

The SY58019UMG is a precision, high-speed differential multiplexer manufactured by Microchip Technology. It operates as a 2:1 MUX with guaranteed AC performance over temperature and voltage. The device supports data throughput up to 10.7Gbps and clock frequencies exceeding 7GHz. It features ultra-low jitter characteristics, including less than 1ps RMS random jitter and less than 10ps peak-to-peak deterministic jitter. The component utilizes a unique input termination architecture that accepts DC-coupled and AC-coupled inputs such as CML, PECL, and LVDS without external level shifting or termination networks. Outputs provide a 400mV LVPECL swing compatible with 100k loads. Power supply requirements are 2.5V ±5% or 3.3V ±10%, and the operating temperature range spans from -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix to confirm package type and lead finish. The 'UMG' designation indicates an MLF-16 package with a Pb-Free NiPdAu lead finish. Confirm whether the part requires tape and reel packaging by checking for the 'TR' suffix in the full part number. Ensure compatibility with the required power supply voltage range of 2.5V or 3.3V during procurement planning.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when low jitter and high-speed data handling are critical. It is suitable for applications requiring interface flexibility with various differential signaling standards like CML, PECL, and LVDS. Consider this part for designs needing internal input termination to simplify the signal path. Compare against the SY58017U if CML outputs are preferred, or the SY58018U if 800mV LVPECL outputs are required.

Signal Switches, Multiplexers, Decoders Part Context

The SY58019UMG belongs to Micrel’s Precision Edge product line, now distributed by Microchip Technology. It is designed for ultra-high-speed digital applications requiring precise timing and minimal signal degradation. The device integrates internal termination resistors to reduce external component count and improve signal integrity in high-frequency environments.

Signal Switches, Multiplexers, Decoders Replacement Considerations

For CML output requirements, consider the SY58017U. For 800mV LVPECL outputs, consider the SY58018U. Both are part of the same Precision Edge family and share similar operational characteristics.
