MK2308S-1H

Overview

The MK2308S-1HLF is a low phase noise, high-speed PLL-based zero delay buffer manufactured by Renesas Electronics. It provides eight low skew outputs operating at frequencies from 10 to 133 MHz with a 3.3 V supply. The device features output-to-output skew of less than 200 ps and device-to-device skew under 700 ps. It operates within a commercial temperature range of 0°C to +70°C and is packaged in a 16-pin SOIC.

Feature Summary

• Zero input-output delay using proprietary PLL techniques
• Eight CMOS outputs with 25 mA drive capability at TTL levels
• Output-to-output skew <200 ps; Device-to-device skew <700 ps
• Tri-state mode for board-level testing

Applications

• Clock distribution in systems requiring synchronization
• Data communications equipment
• Graphics and video processing systems

Procurement Notes

Verify the specific suffix (e.g., LF) against the datasheet ordering table to confirm lead-free status and package type. Confirm that the required temperature range matches the commercial specification (0°C to +70°C), as industrial variants (-40°C to +85°C) use different suffixes such as HI. Check current availability status as this component family may have end-of-life implications.

Selection Notes

Select the MK2308S-1HLF when eight buffered clock outputs are required with minimal skew. Ensure the application frequency does not exceed 133 MHz. Verify that the PCB layout allows for connecting any output to the FBIN pin to enable zero-delay operation. Consider the 16-pin SOIC package dimensions if space constraints exist relative to the TSSOP alternative.

Part Context

This component belongs to the MK2308-1H series of zero delay buffers originally developed by IDT and acquired by Renesas. It is designed to synchronize outputs in various systems by eliminating delay through the device. The 'S' indicates the SOIC package, while 'LF' denotes the lead-free configuration compliant with RoHS standards.

Replacement Considerations

For identical functionality in an SOIC package, consider MK2308S-1HI for industrial temperature ranges or MK2308G-1HLF for a TSSOP package variant. Direct cross-model substitution requires verifying pin compatibility and thermal specifications.
