181MI-02LFT

Overview

The Renesas 181MI-02LFT is a low EMI spread spectrum clock generator housed in an 8-SOIC package. It accepts input frequencies ranging from 28 MHz to 48 MHz and generates a single LVCMOS output within the same frequency range. The device operates at core voltages of 3.3V or 5V. Key jitter specifications include a typical peak-to-peak center-to-center jitter of 250 ps and a maximum of 300 ps. It utilizes proprietary analog and digital Phase-Locked Loop technology to reduce electromagnetic interference.

Feature Summary

• Generates low EMI output clocks using proprietary mixed-signal PLL technology
• Supports single LVCMOS output configuration
• Operates with standard 3.3V or 5V core voltage supplies

Applications

• General-purpose clock generation for digital systems
• Applications requiring reduced electromagnetic interference
• Systems utilizing crystal or external clock inputs

Procurement Notes

Verify component authenticity through authorized channels, as this part may be discontinued or obsolete. Confirm package integrity and pin alignment against the 8-SOIC specification. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions prior to integration into final designs.

Selection Notes

Select this component when a single-channel LVCMOS clock source is required with specific low EMI characteristics. Ensure the design accommodates the 28 MHz to 48 MHz input and output frequency constraints. Verify that the system power supply aligns with the supported 3.3V or 5V operating ranges and that the 8-SOIC footprint fits the PCB layout.

Part Context

This device belongs to the ICS181 series of clock generators manufactured by Renesas Electronics (formerly IDT). These components are designed to replace standard oscillators in applications where electromagnetic compatibility is critical. The 181MI-02LFT specifically denotes the lead-free variant in the SOIC package format.

Replacement Considerations

Direct substitutes include other models from the ICS181 family, such as the ICS181-02, provided they match the required frequency range and package type. Verify functional equivalence regarding jitter performance and voltage compatibility before substitution.
