524SCMGI

Overview

The Renesas 524SCMGI is a low skew, single input to four output LVCMOS clock buffer. It features an extremely low additive phase jitter of 50fs RMS and outputs with 50ps skew. The device supports input/output clock frequencies up to 200MHz and operates on supply voltages ranging from 1.8V to 3.3V. Packaged in an 8-UFDFN (2x2) surface mount format, it utilizes an advanced low-power CMOS process.

Feature Summary

• Provides best-in-class sub-50fs additive phase jitter for high-performance timing applications
• Features direct-coupled signal path suitable for 1pps clocks and allows ICLK driving before VDD application
• Delivers non-inverting output clock signals with extremely low skew characteristics

Applications

• Networking clock distribution systems
• High-speed digital circuit synchronization
• Precision timing infrastructure requiring minimal jitter

Procurement Notes

Verify the specific package variant against project requirements, as the 524S family includes SOIC and DFN options. Confirm that the 8-UFDFN footprint matches the PCB layout constraints. Ensure the operating voltage range aligns with the system power rails. Check the latest datasheet for any updates regarding moisture sensitivity levels or recommended soldering profiles.

Selection Notes

Select this component when sub-50fs jitter performance is critical for signal integrity. The 8-UFDFN package offers a compact solution for space-constrained designs. Consider the 1.8V to 3.3V operating range compatibility with existing logic levels. Evaluate the 200MHz frequency limit against the target clock speed requirements.

Part Context

The 524SCMGI belongs to the 524S series of low skew clock buffers manufactured by Renesas Electronics. This series is designed to provide precise clock distribution with minimal timing errors. The CMGI suffix specifically denotes the 8-UFDFN package type within the broader product line.

Replacement Considerations

The 524SDCGI serves as a pin-compatible alternative within the same series, offering identical electrical specifications but packaged in an 8-SOIC format instead of the DFN configuration.
