MK2304S-1LF

Overview

The MK2304S-1LF is a low jitter, low skew, high performance Phase Lock Loop (PLL) based zero delay buffer designed for high speed applications. It provides four low skew outputs at speeds up to 133 MHz at 3.3 V. The device includes two banks of two outputs each (1X). In the zero delay mode, the rising edge of the input clock is aligned with the rising edges of all 4 outputs. Compared to competitive CMOS devices, it features the lowest jitter.

Feature Summary

• Zero input-output delay using proprietary low jitter PLL techniques
• Output to output skew less than 200 ps
• Spread Smart technology compatible with Spread Spectrum clock generators
• Full CMOS outputs with 8 mA drive capability at TTL levels

Applications

• High speed digital systems requiring precise clock alignment
• Communication equipment utilizing spread spectrum modulation
• Systems needing low jitter clock distribution from a single source

Procurement Notes

Verify the specific suffix requirements for your application. The 'LF' suffix indicates a Pb-Free configuration that is RoHS compliant. Ensure the temperature range matches your needs; commercial versions operate from 0 to +70 °C, while industrial versions support -40 to +85 °C. Confirm packaging type (tube or tape and reel) during ordering.

Selection Notes

Select the MK2304S-1LF when a zero delay buffer with four outputs is required. Ensure the operating voltage is within the 3.0 V to 3.6 V range. For industrial environments, choose the variant with the 'I' suffix (e.g., MK2304S-1ILF). Verify that the load capacitance on outputs does not exceed specifications to maintain the 133 MHz maximum frequency target.

Part Context

This component belongs to the IDT Zero Delay Buffer family, now part of Renesas Electronics Corporation's portfolio following acquisitions. It is an 8-pin SOIC package device designed to replace older buffer technologies with lower jitter performance. The marking diagram identifies the part as '2304S-1L'.

Replacement Considerations

Direct pin-to-pin replacements should be verified against current Renesas datasheets. Check if newer generations offer improved jitter specs or different package options. Ensure any substitute maintains the 3.3V operation and 133 MHz frequency capability.
