MK1709AGLF

Clock Generators, PLLs, Frequency Synthesizers Overview

The MK1709AGLF is an obsolete low EMI clock generator manufactured by Renesas Electronics Corporation (formerly IDT). Packaged in an 8-pin TSSOP, it generates a dithered output clock from a high-speed input to reduce electromagnetic interference. The device utilizes a proprietary analog and digital Phase Locked Loop (PLL) technology to spread the frequency spectrum of the output signal. It operates at a maximum frequency of 165 MHz with a 1:1 input-to-output ratio. The component supports centered spread spectrum modulation, achieving typical peak reductions of 7dB to 14dB on odd harmonics. It functions within a commercial temperature range of 0°C to +85°C and requires a supply voltage between 3.135V and 3.465V.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The MK1709AGLF is officially classified as obsolete. Current availability is limited to existing stock or surplus channels, as production has ceased. Verification of authenticity is critical when sourcing from third-party distributors due to the component's discontinued status. Designers should confirm the specific suffix 'AGLF' corresponds to the lead-free TSSOP package variant before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

This component is suitable for designs requiring simple 1:1 clock dithering without crystal input requirements. For applications necessitating crystal inputs or wider multiplier options, the MK1714-01/02 series is the documented alternative. Engineers must account for the obsolete status when selecting this part for new products, as long-term supply cannot be guaranteed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MK1709 belongs to a family of low EMI clock generators originally developed by Integrated Device Technology (IDT), which was later acquired by Renesas Electronics. The device addresses EMI compliance challenges in digital displays by modulating clock frequencies. It serves as a specialized solution for reducing noise peaks in video signal paths without introducing significant jitter.
