551SCMGI

Overview

The Renesas 551SCMGI is a low skew clock buffer featuring a single input and four outputs. It operates within a supply voltage range of 1.71 V to 3.465 V and supports maximum input frequencies up to 200 MHz. The device exhibits a maximum propagation delay of 4 ns and is housed in an 8-UFDFN surface-mount package. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +105°C.

Procurement Notes

Verify the specific suffix 'GI' against the manufacturer datasheet to confirm package type and material specifications. Confirm RoHS compliance status directly from official documentation before integration. Check current availability as distribution channels may report varying stock levels or lead times.

Selection Notes

Select this component when a 1:4 fan-out ratio is required with low jitter characteristics. Ensure the design accommodates the 1.71 V to 3.465 V operating voltage window. Verify that the 8-UFDFN footprint matches the PCB layout constraints and thermal requirements for the target application environment.

Part Context

This part belongs to the 551S series of clock buffers manufactured by Renesas Electronics. It serves as a signal distribution component within the broader clock and timer IC category, providing signal integrity for synchronous digital circuits.

Replacement Considerations

The 553SCMGI is identified as a parameter-equivalent alternative. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
