180M-01LFT

Overview

The 180M-01LFT is a spread spectrum clock generator IC manufactured by Renesas Electronics Corporation. It operates with a single input-to-output ratio of 1:1 and supports a maximum frequency of 28MHz. The device utilizes a Phase-Locked Loop (PLL) architecture to generate CMOS outputs from crystal or clock inputs. It functions within a supply voltage range of 3.135V to 5.5V and is rated for an operating temperature between 0°C and 70°C. The component is housed in an 8-SOIC package with a width of 3.90mm.

Feature Summary

• Spread spectrum clock generation capability for EMI reduction
• Single channel PLL-based clock generator with 1:1 input-to-output ratio
• CMOS output compatible with standard digital logic interfaces

Applications

• General purpose clock signal generation in embedded systems
• Timing reference distribution for low-speed digital circuits
• EMI mitigation in consumer electronics requiring precise timing

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted to remaining stock, which may be depleted without further replenishment. Verification of current supplier inventory status is required before procurement planning. Alternative components should be evaluated for long-term design sustainability.

Selection Notes

Designers must account for the 28MHz maximum frequency limit when selecting this generator. The 8-SOIC package requires surface mount assembly with specific footprint dimensions. Supply voltage tolerance between 3.135V and 5.5V must be maintained for proper operation. The absence of differential outputs limits use cases to single-ended applications only.

Part Context

The 180M series represents Renesas's legacy spread spectrum clock generators. This specific model belongs to the ICS180 family, designed primarily for reducing electromagnetic interference in digital systems through frequency dithering. It serves as a foundational timing solution for applications where ultra-low jitter is not the primary constraint.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should consult Renesas for updated replacement recommendations due to the EOL status.
