MK1709AG

Clock Generators, PLLs, Frequency Synthesizers Overview

The MK1709AG is a low EMI clock generator IC manufactured by Renesas Electronics Corporation, originally designed by IDT. It utilizes proprietary analog and digital Phase Locked Loop (PLL) technology to spread the frequency spectrum of an input clock, reducing amplitude peaks by 7dB to 14dB on odd harmonics. The device accepts a high-speed clock input and provides a same-frequency dithered output suitable for VGA modes from 25 MHz to 165 MHz. It operates within a supply voltage range of 3.135V to 3.465V and supports an operating temperature range of 0°C to +85°C in an 8-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates low EMI spread spectrum clock outputs from a high-speed clock input using PLL technology.
• Supports flat panel graphics controllers with frequencies ranging from 25 MHz to 165 MHz.
• Features configurable spread percentage and direction via S0, S1, and S2 select pins.
• Includes power-down mode and a Low EMI Enable (LEE) pin to disable spread spectrum functionality.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Flat panel graphics controllers
• LCD interface clock generation
• VGA modes requiring EMI reduction

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity as the MK1709AG is an older component originally from IDT, now under Renesas. Check datasheet revisions and RoHS compliance status, noting that non-green parts had an End-of-Life date in May 2010. Confirm lead-free (LF) suffix availability if environmental compliance is required for current manufacturing processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the MK1709AG when a fixed-ratio (1:1) clock generator with spread spectrum capabilities is needed for LCD interfaces. Ensure the input clock frequency falls within the 25-165 MHz range. Consider the 8-pin TSSOP package constraints and verify that the required spread percentage matches the configurations available via the S0-S2 pin logic table.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MK1709AG is part of the MK1709 family of low EMI clock generators. It is specifically the 8-pin TSSOP variant, distinct from the SOIC package version (MK1709S). The device was originally developed by Integrated Device Technology (IDT) before being acquired by Renesas Electronics Corporation.
