MK1714-01R

Clock Generators, PLLs, Frequency Synthesizers Overview

The MK1714-01R is a spread spectrum multiplier clock synthesizer in a 20-pin SSOP package. It accepts a 10–25 MHz crystal or 10–150 MHz clock input to generate outputs from 20–150 MHz using multipliers x1 through x6. The device uses analog/digital PLL techniques to reduce EMI amplitude peaks at odd harmonics by several dB via selectable center, down, or combined spread modes. Operating voltage is 3.3V or 5V with supply currents of 26 mA (3.3V) and 40 mA (5V). The commercial temperature range is 0°C to +70°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Spread spectrum modulation reduces EMI peaks at odd harmonics
• Configurable multipliers: x1, x2, x3, x4, x5, and x6
• Selectable center, down, or combined frequency spread
• Supports both crystal and direct clock inputs

Clock Generators, PLLs, Frequency Synthesizers Applications

• Flat panel graphics controllers
• Computer peripherals requiring low EMI clocks
• Systems needing single-source clock generation

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix for the required temperature grade and packaging. The 'R' suffix indicates the standard commercial temperature range (0°C to +70°C). Ensure lead-free ('LF') variants are selected if RoHS compliance is mandatory. Confirm availability as non-green parts have an established end-of-life date.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select based on the required output frequency and input source type. Use the S4:S0 pin configuration table to determine the correct multiplier and spread amount. For crystal inputs, connect XSEL to VDD; for clock inputs, connect XSEL to GND. Ensure decoupling capacitors are placed close to VDD pins without vias.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the IDT Spread Spectrum Multiplier Clock family. It is functionally related to the MK1714-02, which offers different input ranges and spread options. The device replaces multiple discrete crystals and oscillators to save board space.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MK1714-02 is a related part within the same family offering alternative input frequency selections and spread configurations. Verify compatibility of the S4:S0 logic levels and pinout before substitution.
