MK2304S-2I

Overview

The MK2304S-2I is a zero delay, low skew buffer manufactured by Renesas Electronics (formerly IDT). It utilizes a Phase Lock Loop (PLL) to provide four low skew outputs at speeds up to 133 MHz at 3.3 V. The device includes two 1X outputs and two 1/2X outputs. In zero delay mode, the rising edge of the input clock aligns with all output rising edges. It operates within an industrial temperature range of -40°C to +85°C and features less than 200 ps output-to-output skew.

Feature Summary

• Zero input-output delay alignment
• Four outputs: two 1X and two 1/2X
• Output-to-output skew < 200 ps
• Industrial temperature range (-40°C to +85°C)

Applications

• High speed digital systems requiring precise clock distribution
• Systems utilizing spread spectrum clock generators
• Applications needing low jitter clock buffering

Procurement Notes

Verify component authenticity as this part was originally manufactured by Integrated Device Technology (IDT), which has since merged into Renesas Electronics. Confirm RoHS compliance status, noting that non-green parts had an end-of-life date in May 2010. Ensure the specific suffix 'I' denotes the industrial temperature grade required for the application environment.

Selection Notes

Select the MK2304S-2I when an industrial temperature rating (-40°C to +85°C) is required. The standard commercial version (MK2304S-2) operates from 0°C to +70°C. This model provides four outputs including divide-by-two capabilities, suitable for systems needing both full-speed and half-speed clock signals derived from a single source.

Part Context

This component belongs to the MK2304-2 series of zero delay buffers. It is part of the ClockBlocks family designed for high-performance clock distribution. The 'S' indicates an SOIC package, and the 'I' suffix specifies the industrial temperature operating range, distinguishing it from commercial variants.

Replacement Considerations

Direct replacements include other MK2304-2 variants such as MK2304S-2ITR (tape and reel) or MK2304S-2ILF (lead-free). Cross-manufacturer equivalents should be evaluated based on pin compatibility, voltage levels, and skew specifications.
