MK2302S-01LF

Clock Generators, PLLs, Frequency Synthesizers Overview

The MK2302S-01LF is a high-performance Zero Delay Buffer (ZDB) and clock multiplier from the ClockBlocks family, originally manufactured by IDT and now associated with Renesas Electronics. It integrates proprietary analog/digital Phase-Locked Loop (PLL) techniques to align input clock rising edges with output clocks, eliminating apparent device delay. The device features two outputs: CLK1 provides selectable multiplication factors ranging from 0.5X to 16X, while CLK2 offers a low-skew divide-by-two of CLK1. It supports operating voltages of 3.3V or 5V, achieving output frequencies up to 168MHz at 3.3V. Key electrical parameters include a maximum input-to-output skew of 250ps, absolute jitter of ±500ps, and propagation delay of ±350ps.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero Delay Buffer architecture synchronizes input clock rising edges with both output clocks.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity as this part was originally an IDT product before acquisition. Confirm RoHS compliance status, noting that non-green parts reached End-of-Life on May 13, 2010. Ensure the specific suffix matches the required temperature range and packaging format, as availability may be limited due to age.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the MK2302S-01LF for designs requiring precise clock alignment without internal delay. Choose the industrial version (suffix -ILF) if operation between -40°C and +85°C is required. Ensure external feedback paths are connected correctly to FBIN to utilize the zero-delay feature effectively.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the ClockBlocks family of clock management ICs. While marketed under Renesas Electronics in current databases, the datasheet identifies Integrated Device Technology (IDT) as the original manufacturer. The 'LF' suffix denotes a lead-free, RoHS-compliant package configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life notification for non-green parts dated May 13, 2010, direct replacements should be sought from current Renesas or IDT clock buffer portfolios.
