SY58023UMG

Signal Switches, Multiplexers, Decoders Overview

The SY58023UMG is a precision, high-speed, fully differential CML 2x2 crosspoint switch manufactured by Microchip Technology. It operates from +2.5V ±5% or +3.3V ±10% supplies and supports data rates up to 10.7 Gbps with clock signals as fast as 6 GHz. The device features ultra-low jitter performance, including less than 10 ps peak-to-peak total jitter for clocks and less than 1 ps RMS random jitter for data. It accepts input signals as low as 100 mV via LVPECL, LVDS, or CML interfaces without external level-shifting. The component is housed in a 16-pin MLF package and functions within an industrial temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific part number suffix matches the required packaging configuration, such as tube versus tape and reel. Confirm RoHS compliance status and lead finish options (Sn-Pb vs NiPdAu) against current manufacturing specifications. Ensure the procurement source provides valid traceability documentation for the industrial temperature grade components.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single 2x2 crosspoint switch with CML outputs is required. For applications needing dual independent switches, consider the SY58024U instead. Verify that the system power supply voltage aligns with the specified 2.5V or 3.3V operating ranges. Ensure the PCB layout accommodates the 16-pin MLF package dimensions and thermal requirements.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to Micrel's Precision Edge product line, which focuses on high-speed signal integrity solutions. It serves as a core switching element in high-bandwidth communication infrastructure. The device integrates internal termination to simplify board design compared to discrete switching solutions.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The SY58024U is documented as a related product offering dual 2x2 crosspoint switches. Direct pin-for-pin substitution with other series members requires verification of electrical characteristics and pinout compatibility through official datasheets.
