MK2302S-01ILFTR

Overview

The MK2302S-01ILFTR is a high-performance Zero Delay Buffer (ZDB) and clock multiplier from the ClockBlocks family. It integrates 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 specifications include a maximum input-to-output skew of 250ps, absolute jitter of ±500ps, and propagation delay of ±350ps.

Feature Summary

• Zero Delay Buffer architecture synchronizes input and output clock rising edges via off-chip feedback paths.
• Configurable multipliers from 0.5X to 16X selected via S0/S1 pins; includes dedicated low-skew divide-by-two output.
• Low jitter performance with absolute jitter ±500ps and input-to-output skew max 250ps.
• Operates on 3.3V or 5V supplies with full CMOS swings and 25mA drive capability.

Applications

• Synchronizing outputs in personal computer systems.
• Clock distribution in data communications equipment.
• Graphics and video processing synchronization.

Procurement Notes

Verify component status as the datasheet indicates End-of-Life (EOL) for non-green parts occurred on May 13, 2010. Confirm that the specific ordering suffix corresponds to the RoHS-compliant lead-free configuration required for current manufacturing standards. Check availability through authorized distributors for remaining stock or qualified replacement alternatives.

Selection Notes

Select this component when zero-delay synchronization between input and multiple output clocks is required. Ensure the system operates within the specified voltage range of 3.3V or 5V. Verify that the required output frequency does not exceed 168MHz at 3.3V. Consider the industrial temperature range (-40°C to +85°C) if applicable, as indicated by the 'I' suffix in the part number.

Part Context

This device belongs to the IDT ClockBlocks family, designed as a performance upgrade for higher speed and lower voltage requirements. It utilizes proprietary PLL technology to recover degraded input duty cycles and eliminate delays through other devices in the signal chain. The 'R' suffix denotes tape and reel packaging.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status of non-green parts, verify compatibility with newer Renesas or IDT ZDB models offering similar pinouts and electrical characteristics.
