MK5814GLFTR

Overview

The MK5814GLFTR is a low EMI clock generator manufactured by Renesas Electronics Corporation, packaged in an 8-pin TSSOP. It utilizes IDT’s proprietary analog and digital Phase Locked Loop (PLL) technology to generate spread spectrum output clocks from a clock or crystal input. The device features a fixed 4x frequency multiplication, accepting inputs between 4 MHz and 32 MHz to produce outputs ranging from 16 MHz to 128 MHz. Operating at 3.3 V with advanced low-power CMOS process, it reduces peak emissions by 8 dB to 16 dB on odd harmonics. Supply current ranges from 23 mA to 35 mA depending on input frequency.

Feature Summary

• Fixed 4x frequency multiplication with input range of 4–32 MHz and output range of 16–128 MHz
• Spread spectrum capability with center and down spread options for EMI reduction
• Tri-level select pins (S0, S1) for configurable spread direction and percentage
• Includes power-down mode and supports flat panel controller applications

Applications

• Flat panel controllers
• Consumer electronics requiring low EMI clock generation
• Systems needing removal of crystals and oscillators from the board

Procurement Notes

Verify component authenticity through authorized channels as the part originates from Integrated Device Technology (IDT), now part of Renesas. Confirm package type matches the 8-pin TSSOP specification. Check RoHS compliance status if required by local regulations. Ensure supply chain stability as electronic components may face availability fluctuations.

Selection Notes

Select this component when a fixed 4x multiplier is required for clock synthesis. Compare against MK5811 (1x) and MK5812 (2x) if different multiplication ratios are needed. Ensure input frequency falls within the 4–32 MHz range. Verify that the 8-pin TSSOP package fits the PCB layout constraints.

Part Context

The MK5814 series belongs to the IDT Low EMI Clock Generator family, designed to dither high-emission clocks for consumer applications. This specific suffix 'GLFTR' denotes the Tape and Reel shipping packaging variant in the 8-pin TSSOP package. The device replaces discrete crystal and oscillator solutions to simplify board design.

Replacement Considerations

For 1x multiplication, consider MK5811. For 2x multiplication, consider MK5812. These parts share similar low EMI characteristics but differ in frequency multiplication ratios. Verify pin compatibility and electrical specifications before substitution.
