SY56020RMG

Clock Buffers, Drivers Overview

The SY56020RMG is a fully-differential, low-voltage CML 1:4 fanout buffer manufactured by Microchip Technology. It supports data rates up to 6.4 Gbps and clock frequencies up to 4.5 GHz. The device features input equalization for transmission lines of 9, 18, or 27 inches. It operates with a 2.5V ±5% core supply (VCC) and a selectable 1.2V, 1.8V, or 2.5V ±5% output supply (VCCO). Key electrical parameters include a propagation delay of less than 280 ps, within-device skew under 15 ps, and rise/fall times under 90 ps. Random jitter is specified at less than 1 ps RMS.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix when sourcing components. The 'MG' suffix indicates a QFN-16 package with an industrial operating range and NiPdAu lead finish. Confirm that the required quantity matches the standard tube packaging associated with this suffix, as tape and reel options utilize a different designation.

Clock Buffers, Drivers Selection Notes

Select the appropriate VCCO voltage (1.2V, 1.8V, or 2.5V) based on the downstream receiver requirements. Ensure the input signal amplitude meets the minimum swing specifications before the transmission line. For AC-coupled inputs, connect the VT pin to VCC via a low-ESR capacitor to utilize the internal bias network.

Clock Buffers, Drivers Part Context

The SY56020RMG belongs to Micrel’s Precision Edge product line, which focuses on high-speed timing solutions. This component serves as a fanout buffer within the SY56020R family, providing four differential outputs from a single differential input while maintaining signal integrity over significant PCB trace lengths.
