MK2304S-2

Overview

The MK2304S-2 is a zero delay buffer IC manufactured by Renesas Electronics Corporation, originally designed by IDT. It utilizes a Phase Lock Loop (PLL) to align the rising edge of the input clock with four low skew outputs. The device provides two 1X outputs and two 1/2X outputs, supporting frequencies up to 133 MHz at 3.3 V. It operates within a commercial temperature range of 0°C to 70°C and features Spread Smart technology for spread spectrum applications.

Feature Summary

• Zero input-output delay alignment via PLL feedback
• Four outputs: two 1X and two 1/2X frequency ratios
• Output-to-output skew less than 200 ps on the same bank
• Spread Smart technology compatible with spread spectrum generators

Applications

• High-speed data communications systems
• Personal computer synchronization
• Graphics and video processing circuits

Procurement Notes

Verify component status as non-green parts reached End-of-Life on May 13, 2010. Confirm availability of lead-free (LF) variants which are RoHS compliant. Ensure ordering suffixes match required packaging and temperature specifications.

Selection Notes

Select industrial temperature versions (-40°C to 85°C) if operating conditions exceed commercial limits. Choose tape and reel packaging for automated assembly or tubes for manual handling. Verify 3.3V supply requirements and 8 mA drive capability compatibility with load capacitance.

Part Context

This component belongs to the IDT Zero Delay Buffer family, now under Renesas Electronics. It serves as a high-performance clock distribution solution designed to eliminate propagation delay through the device by aligning output edges directly with the input reference.

Replacement Considerations

Consult official documentation for direct substitutes. Note that the MK2304-2 has reached end-of-life status for non-green configurations.
