SY56020XRMG-TR

Clock Buffers, Drivers Overview

The SY56020XRMG-TR is a low voltage CML 1:4 fanout buffer with input equalization, operating at data rates up to 6.4Gbps and clock frequencies up to 4.5GHz. It features a unique 3-pin input termination architecture supporting DC-coupled LVPECL (2.5V/3.3V), CML (1.2V/1.8V/2.5V), or LVDS signals. The device uses a 2.5V ±5% core supply and a selectable 1.2V, 1.8V, or 2.5V output supply. Key performance metrics include less than 300ps propagation delay, under 15ps within-device skew, and ultra-low jitter specifications of <0.8ps RMS random jitter and <10ps peak-to-peak deterministic jitter.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' corresponds to the Tape and Reel packaging variant as specified in the manufacturer's documentation. Confirm that the NiPdAu lead finish and QFN-16 package dimensions align with the target PCB layout requirements. Ensure the industrial temperature range (-40°C to +85°C) meets the operational environment standards.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential input must be distributed to four CML outputs with minimal skew. The three-level EQ control allows optimization for specific FR4 transmission line lengths (9, 18, or 27 inches). Verify compatibility with the source signal type (LVPECL, CML, or LVDS) and ensure the VCCO supply voltage matches the required output swing levels.

Clock Buffers, Drivers Part Context

The SY56020XR belongs to Micrel’s Precision Edge product line, designed for high-speed interface applications. The 'MG' suffix indicates the 16-pin QFN package, while 'TR' denotes the tape and reel shipping configuration. This part is functionally related to other devices in the SY560xx series, such as the SY56011R (1:2 fanout) and SY56028XRMG (4:1 mux with fanout).
