MK1413S

Overview

The MK1413 is an MPEG audio clock source synthesizer manufactured by Integrated Device Technology (IDT). It generates four specific frequencies from a 14.31818 MHz reference using analog and digital PLL technology. The device operates on a 3.0 V to 5.5 V supply with a typical current of 12 mA at 5 V. It provides low jitter outputs with rise/fall times of 1.5 ns and supports TTL-level drive capability of 25 mA. Packaged in an 8-pin SOIC, it replaces mechanical oscillators to reduce board space.

Feature Summary

• Synthesizes 8.192 MHz, 11.2896 MHz, 12.288 MHz, and 16.9344 MHz from a 14.31818 MHz input
• Supports 32 kHz, 44.1 kHz, and 48 kHz sampling rates for MPEG audio devices
• Low jitter performance with 200 ps absolute period jitter and 70 ps one sigma jitter
• 25 mA drive capability at TTL levels with 3.3 V or 5.0 V supply voltage

Applications

• Generating master clocks for MPEG audio devices in computers
• Digital audio signal processing applications requiring precise sampling rates
• Equipment control systems utilizing standard audio frequencies

Procurement Notes

Verify the manufacturing origin as IDT/ICS rather than Renesas, as the datasheet identifies Integrated Device Technology as the manufacturer. Confirm RoHS compliance status, noting that non-green parts reached end-of-life on May 13, 2010. Check for ordering suffixes such as 'LF' for lead-free configurations or 'TR' for tape and reel packaging when sourcing replacements.

Selection Notes

Select the MK1413 when replacing crystals and oscillators in MPEG audio circuits to save component count and board space. Ensure the design accommodates a 14.31818 MHz crystal input or clock signal. Verify that the required output frequency matches one of the four synthesized options controlled by S0 and S1 pins. Consider PCB layout guidelines for decoupling and trace impedance to maintain signal integrity.

Part Context

The MK1413 belongs to the family of MPEG audio clock sources offered by IDT/ICS. It is designed to eliminate expensive mechanical devices from computer boards. The device utilizes a proprietary mixture of analog and digital PLL technology to synthesize frequencies accurately. It is intended for normal commercial applications and not recommended for extended temperature ranges without additional processing.

Replacement Considerations

Parts ordered with a "LF" suffix are Pb-Free and RoHS compliant. Non-green parts reached end-of-life on 5/13/10. The MK1413STR and MK1413SLFTR are available in Tape and Reel packaging. Consult IDT for other compatible clocks if different specifications are required.
