MK5811CMILF

Overview

The MK5811CMILF is a low EMI clock generator manufactured by Renesas Electronics Corporation, packaged in an 8-pin SOIC (0.154 inch width). It operates within a supply voltage range of 3V to 3.63V and supports a maximum frequency of 32MHz. The device features a single circuit with a 1:1 input-to-output ratio and utilizes LVCMOS output logic. Designed for surface mount installation, it functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Generates low EMI output clocks using proprietary analog and digital PLL technology
• Supports spread spectrum output with center and down spread modes
• Accepts clock or crystal inputs to provide dithered same-frequency outputs
• Includes power-down functionality and peak reduction of 8 dB to 16 dB on odd harmonics

Applications

• Printers
• Flat panel controllers

Procurement Notes

Verify the specific suffix 'C' against official documentation, as it denotes the commercial temperature grade (-40°C to 85°C) distinct from industrial variants. Confirm current manufacturing status, as this component may be obsolete or subject to product change notices. Ensure compatibility with RoHS3 specifications if required by the target assembly process.

Selection Notes

Select this component when low electromagnetic interference is critical for consumer applications operating at frequencies between 4MHz and 32MHz. The 1:1 ratio makes it suitable for direct clock distribution without frequency multiplication. Verify that the 3.3V nominal supply voltage aligns with the system's power rails and that the 8-SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the MK5811 family of low EMI clock generators originally developed by IDT and acquired by Renesas. It serves as a specialized solution for reducing radiated emissions in high-speed digital systems. Related parts in the series include the MK5812 for 2x multiplication and the MK5814C for 4x multiplication configurations.

Replacement Considerations

Public records indicate the MK5811CMILF is obsolete. Potential replacements include other low EMI clock generators from Renesas or compatible devices offering similar 32MHz spread spectrum capabilities in an 8-SOIC package.
