2402MLF

Overview

The Renesas 2402MLF is a Zero Delay Buffer (ZDB) IC from the ClockBlocks family, designed for high-performance clock synchronization. It integrates an analog/digital Phase-Locked Loop (PLL) to align input and output rising edges, eliminating apparent propagation delay. The device operates on a single 3.15V to 5.5V supply and supports maximum frequencies up to 80MHz. It features a multiplier function providing a 2X output clock frequency with full CMOS swings and 25mA drive capability at TTL levels. Packaged in an 8-SOIC format, it functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero Delay Buffer architecture aligns input and output clock edges via off-chip feedback.
• Integrates PLL technology for jitter performance of ±100 ps absolute jitter.
• Provides 2X output clock multiplication with propagation delay of ±600 ps.
• Recovers degraded input clock duty cycles to ensure stable 45/55 output duty cycle.

Applications

• Synchronizing outputs in personal computer systems.
• Data communications infrastructure requiring precise timing.
• Graphics and video processing applications needing low-jitter clocks.

Procurement Notes

The 2402MLF is officially listed as obsolete by Renesas Electronics Corporation. Product Change Notices indicate discontinuation effective April 26, 2018. Availability is restricted to existing stock or last-time buys; new design-in is prohibited. Verification of genuine sourcing is critical due to the end-of-life status.

Selection Notes

Select this component only if legacy compatibility with IDT ClockBlocks architecture is required. Ensure the system design accommodates the 8-SOIC package and 3.15V–5.5V supply range. For new designs, consider modern replacements as this part is discontinued. Verify that the 80MHz maximum frequency meets the specific application requirements.

Part Context

This component belongs to the Renesas (formerly IDT) ClockBlocks family of clock generators and buffers. The 2402 series was engineered as a performance upgrade for higher speed and lower voltage demands compared to earlier generations. It utilizes advanced low-power CMOS processes to deliver high-drive capabilities while maintaining strict timing specifications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements must be identified through current manufacturer catalogs or authorized distributor cross-reference tools.
