553SCMGI

Overview

The Renesas Electronics Corporation 553SCMGI is a low skew, single-input to four-output LVCMOS clock buffer from the 553S series. It supports input and output clock frequencies up to 200 MHz with a maximum propagation delay of 4 ns. The device operates on a supply voltage range of 1.71 V to 3.465 V and consumes approximately 22 mA of operating current. It is housed in an 8-UFDFN (2x2 mm) surface-mount package and functions within an extended temperature range of -40°C to +105°C.

Feature Summary

• Low skew performance with sub 50fs additive phase jitter
• Single input to four output clock distribution ratio
• LVCMOS output type compatible with standard logic levels
• Extended industrial temperature range (-40°C to +105°C)

Applications

• Networking clock distribution systems
• General-purpose clock buffering for digital circuits
• Low-power CMOS process applications requiring precise timing

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified suppliers. Confirm RoHS3 compliance status and check for recent Process Change Notices (PCN) regarding packaging or material updates before procurement. Ensure the 8-VFQFN package dimensions match the target PCB footprint requirements.

Selection Notes

Select the 553SCMGI when a 1:4 fan-out buffer with low skew is required for signals up to 200 MHz. Compare against the 551SCMGI if parameter equivalence is acceptable. Ensure the design accommodates the 1.71V to 3.465V supply range and the specific thermal characteristics of the 8-UFDFN package for the intended operating environment.

Part Context

The 553SCMGI belongs to the 553S family of clock buffers designed for networking and general timing applications. This series utilizes an advanced, low-power CMOS process to deliver high-performance clock distribution with minimal power consumption. The component serves as a critical interface for synchronizing multiple downstream components in high-speed digital systems.

Replacement Considerations

The 551SCMGI is listed as a parameter-equivalent substitute by Renesas Electronics Corporation.
