SY58012UMI

Clock Buffers, Drivers Overview

The SY58012UMI is a precision, high-speed, fully differential 1:2 LVPECL fanout buffer manufactured by Microchip Technology. It operates from a 2.5V ±5% or 3.3V ±10% supply voltage and supports clock signals up to 5 GHz or 5 Gbps data rates. The device features guaranteed AC performance including less than 110 ps rise/fall times, less than 260 ps propagation delay, and less than 15 ps maximum skew. It incorporates unique internal input termination that accepts DC- and AC-coupled differential inputs (LVPECL, LVDS, CML) as low as 100 mV without external level-shifting networks. The component is housed in a 16-pin, 3 mm x 3 mm QFN package.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'MI' against official documentation to confirm specific packaging or temperature range variations. Confirm RoHS compliance status through the manufacturer's current product specifications. Ensure the selected variant matches the required industrial temperature range of –40°C to +85°C.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew, high-speed LVPECL fanout buffer is required. It is suitable for applications needing to interface with LVPECL, LVDS, or CML sources using internal termination. Consider the SY58013U if a 400 mV output swing is needed, or the SY58011U for CML outputs.

Clock Buffers, Drivers Part Context

The SY58012U belongs to Microchip’s Precision Edge® product line of high-speed logic devices. The 'M' suffix indicates the 3 mm x 3 mm QFN-16 package, while 'G' denotes the industrial temperature range. This specific part number represents a variant within the SY58012U family designed for precise signal buffering.

Clock Buffers, Drivers Replacement Considerations

For higher bandwidth requirements, consider the SY58013U which offers a 400 mV output swing. For CML input/output compatibility, the SY58011U is an alternative within the same series.
