621SCMGI

Overview

The Renesas 621SCMGI is a low skew clock buffer within the 621S series, designed for high-speed digital systems. It functions as a 1-to-4 fan-out buffer with a maximum operating frequency of 200 MHz. The device supports supply voltages ranging from 1.71 V to 3.465 V and operates across an ambient temperature range of -40°C to +105°C. It utilizes an 8-VFQFN (2x2) surface-mount package. Key electrical characteristics include a typical propagation delay of 4.5 ns and low jitter performance suitable for precision timing applications.

Part Context

The 621SCMGI belongs to the 621S family of clock buffers manufactured by Renesas Electronics. This series is engineered to provide precise clock signal distribution with minimal skew, ensuring synchronization integrity in complex multi-clock domain designs. The component serves as a critical interface between primary oscillators and downstream synchronous logic.

Replacement Considerations

Public documentation identifies the 621SCMGI8 as a compatible variant within the same product line, distinguished primarily by its reel packaging configuration compared to the tube packaging of the base model.
