553MLFT

Overview

The Renesas Electronics 553MLFT is a low skew, single-input to four-output clock buffer belonging to the ClockBlocks family. It operates within a supply voltage range of 2.375 V to 5.25 V and supports maximum input frequencies up to 200 MHz. The device features a propagation delay of 5 ns maximum and is housed in an 8-SOIC package with a width of 3.90 mm. Designed for surface-mount installation, it functions across commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. The component utilizes low power CMOS technology and includes an output enable pin to tri-state outputs.

Feature Summary

• Low skew performance with 50 ps maximum output skew
• Single input to four output configuration
• Operating supply voltage from 2.375 V to 5.25 V
• Maximum input frequency of 200 MHz

Applications

• Clock distribution networks requiring low skew
• High-speed digital systems synchronization
• Commercial and industrial electronic equipment

Procurement Notes

Verify the specific suffix 'MLFT' against official Renesas documentation to confirm tape-and-reel packaging versus tube packaging variants. Confirm RoHS compliance status and moisture sensitivity level directly from the manufacturer datasheet prior to procurement. Ensure the ordering quantity aligns with the specified carrier type to avoid packaging discrepancies.

Selection Notes

Select the 553MLFT when a 1-to-4 fan-out buffer with low skew characteristics is required. Compare against the 553SDCGI8 if lower voltage operation (1.71 V to 3.465 V) or improved jitter performance is necessary. Verify that the 200 MHz maximum input frequency meets system requirements and that the SOIC-8 package fits the PCB layout constraints.

Part Context

The 553MLFT is part of the Renesas ClockBlocks family, which provides various clock buffering and generation solutions. It serves as a successor or alternative to earlier IDT clock buffer designs. The device is distinct from the 553MILF primarily by its packaging format, while sharing similar electrical specifications and functionality within the 553M series.

Replacement Considerations

The 553SDCGI8 offers improved jitter performance and operates at lower voltages but requires a different supply range. The 551MILFT provides similar functionality but has a lower maximum input frequency of 160 MHz. Verify pin compatibility and electrical parameters before substituting.
