SY56020XRMG

Clock Buffers, Drivers Overview

The SY56020XRMG is a low voltage CML 1:4 fanout buffer with input equalization, manufactured by Microchip Technology. It supports data rates up to 6.4 Gbps and processes clock signals as fast as 4.5 GHz. The device operates from a 2.5V ±5% core supply (VCC) and a 1.2V, 1.8V, or 2.5V ±5% output supply (VCCO). It features ultra-low jitter design with less than 0.8ps RMS random jitter and less than 10ps peak-to-peak deterministic jitter. Propagation delay is guaranteed at less than 300ps, with within-device skew under 15ps. The component is available in a 16-pin QFN package and operates over the industrial temperature range of –40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix RMG corresponds to the QFN-16 package type with NiPdAu lead finish and Pb-Free status. Confirm that the part number includes the specific bar-line indicator marking for identification. Ensure the procurement matches the Industrial operating temperature range specifications provided in the datasheet.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:4 fanout buffer with input equalization is required for high-speed CML applications. Consider the three-level EQ input control for adjusting signal integrity across different FR4 transmission line lengths (9, 18, or 27 inches). Verify power supply requirements match the 2.5V core and 1.2V/1.8V/2.5V output options.

Clock Buffers, Drivers Part Context

The SY56020XRMG belongs to Micrel’s Precision Edge product line, which focuses on high-speed timing components. It is designed to interface with various differential signal standards including LVPECL, CML, and LVDS through its unique 3-pin input termination architecture. The device provides buffered copies of the input signal across four differential output pairs.
