MK5814CMLF

Overview

The MK5814CMLF is a low EMI clock generator manufactured by Renesas Electronics, packaged in an 8-pin SOIC. It utilizes analog and digital PLL technology to dither high-emission clocks, reducing frequency amplitude peaks by 8 dB to 16 dB on odd harmonics. The device accepts a 4 MHz to 32 MHz input and provides a fixed 4x multiplication, yielding a 16 MHz to 128 MHz output. Operating at 3.3 V with advanced low-power CMOS process, it supports center and down spread spectrum configurations via tri-level select pins.

Feature Summary

• Fixed 4x frequency multiplication with input range of 4-32 MHz and output range of 16-128 MHz
• Low EMI performance with typical peak reduction of 8 dB to 16 dB on 3rd through 19th odd harmonics
• Configurable spread spectrum modes including center (±0.5% to ±1.4%) and down (-0.7% to -3.0%) via S1/S0 pins
• Supports crystal or clock input with integrated power-down capability

Applications

• Printers
• Flat panel controllers
• Consumer electronics requiring low EMI clock generation

Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm RoHS compliance and lead-free packaging specifications for the specific ordering suffix. Ensure supply chain availability aligns with production timelines given potential end-of-life constraints.

Selection Notes

Select this component when a fixed 4x multiplier is required for frequencies up to 128 MHz. Compare against MK5811C (1x) or MK5812 (2x) if different multiplication ratios are needed. Ensure the application environment operates within the 0°C to +85°C temperature range and utilizes a 3.3 V power supply.

Part Context

The MK5814C belongs to the IDT/ICS Low EMI Clock Generator family. It is designed to replace crystals and oscillators in consumer applications by spreading the frequency spectrum. Related parts include the MK5811C and MK5812, which offer 1x and 2x multiplication respectively.

Replacement Considerations

For equivalent functionality with different multipliers, consider the MK5811C (1x) or MK5812 (2x). Verify pin compatibility and electrical characteristics against current design requirements.
