MK2304S-2ILF

Overview

The MK2304S-2ILF is a zero delay, low skew buffer manufactured by Renesas Electronics Corporation (formerly IDT). It utilizes a Phase Lock Loop (PLL) to align the rising edge of the input clock with four outputs. The device provides two 1X outputs and two 1/2X outputs, operating at speeds up to 133 MHz at 3.3 V. It features output-to-output skew of less than 200 ps and operates within an industrial temperature range of -40°C to +85°C in an 8-pin SOIC package.

Feature Summary

• Zero delay mode aligns input clock rising edges with all four outputs
• Provides two 1X outputs and two 1/2X outputs
• Output-to-output skew is less than 200 ps
• Operates at frequencies from 10 MHz to 133 MHz at 3.3 V

Applications

• High speed digital systems requiring precise clock distribution
• Industrial applications requiring extended temperature operation
• Systems utilizing spread spectrum clock generators

Procurement Notes

Verify the specific ordering suffix for packaging requirements. The 'LF' suffix indicates lead-free and RoHS compliance. Confirm whether tube or tape and reel shipping is required for the design implementation. Ensure the industrial temperature grade (-40°C to +85°C) matches the environmental specifications.

Selection Notes

Select this component when low jitter and zero delay buffering are critical for system timing. The MK2304S-2ILF supports frequencies up to 133 MHz with a 3.3 V supply. Consider the 8 mA drive capability and the requirement for external decoupling capacitors and series terminating resistors for optimal signal integrity.

Part Context

This part belongs to the MK2304-2 family of zero delay buffers. The 'I' suffix denotes the industrial temperature range variant, while 'LF' confirms lead-free construction. The device is based on IDT's proprietary low jitter PLL techniques, designed to outperform standard CMOS devices in jitter performance.

Replacement Considerations

The datasheet does not list official replacement part numbers. Designers should verify pin compatibility and electrical parameters if considering alternative vendors. Check for availability of the specific industrial temperature grade variant.
