180M-53LFT

Overview

The Renesas 180M-53LFT is a spread spectrum clock generator IC designed for low EMI applications. It operates within a supply voltage range of 3.135V to 5.5V and supports output frequencies from 15MHz to 28MHz. The device features a single LVCMOS output with a 1:1 input-to-output ratio. It is housed in an 8-SOIC package (0.154" width) and functions reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Generates clock signals with spread spectrum modulation to reduce electromagnetic interference.
• Provides a single LVCMOS output signal derived from the internal PLL.
• Operates on standard 3.3V or 5V logic power supplies.

Applications

• Low EMI clock generation for digital systems
• Spread spectrum clocking for processors and memory interfaces
• General purpose clock distribution in consumer electronics

Procurement Notes

Verify component authenticity through authorized channels, as this part may be subject to end-of-life status or obsolescence notices. Confirm that the specific suffix 'LFT' corresponds to the required tape-and-reel packaging format if applicable. Ensure compatibility with existing board layouts and voltage levels before procurement.

Selection Notes

Select this component when spread spectrum clocking is required to minimize radiated emissions in systems operating between 15MHz and 28MHz. It is suitable for designs requiring a single CMOS output without differential signaling needs. Consider the 8-SOIC package constraints and surface-mount assembly requirements during PCB design.

Part Context

This device belongs to the Renesas 180M series of clock generators, which are engineered for noise reduction in high-speed digital circuits. The 180M-53LFT specifically targets applications where electromagnetic compatibility is critical, offering a compact solution for frequency synthesis and jitter management in embedded systems.
