MK2308S-1HI

Overview

The MK2308S-1HI is a low phase noise, high-speed PLL-based clock buffer featuring eight outputs. It operates as a zero delay buffer with input-to-output skew of ±250 ps and output-to-output skew under 200 ps. The device supports frequencies from 10 to 133 MHz at a 3.3 V supply. It utilizes an advanced sub-micron CMOS process for low power consumption. The component is housed in a 16-pin SOIC package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

• Zero delay buffer architecture aligns rising edges of input and output clocks
• Eight low skew outputs with <200 ps device-to-device skew
• Full CMOS outputs providing 25 mA drive capability at TTL levels
• 5 V tolerant CLKIN and FBIN pins

Applications

• Personal computer systems
• Data communications equipment
• Graphics and video synchronization

Procurement Notes

Verify the specific suffix 'HI' confirms the industrial temperature range (-40°C to +85°C) and 16-pin SOIC packaging. Confirm RoHS compliance status if lead-free requirements are mandatory, as non-green parts have reached end-of-life. Ensure the source document matches the Renesas Electronics Corporation branding following the IDT acquisition.

Selection Notes

Select this component when zero input-to-output delay is required for system synchronization. The MK2308S-1HI is suitable for applications needing up to eight buffered clock signals with minimal skew. Verify that the 3.3 V operating voltage and 133 MHz maximum frequency meet the design specifications. Consider the 16-pin SOIC footprint for PCB layout compatibility.

Part Context

This part belongs to the MK2308-1H family of clock buffers originally manufactured by Integrated Device Technology (IDT). Following the acquisition of IDT by Renesas Electronics Corporation, these products are now distributed under the Renesas brand. The device is part of the ClockBlocks™ family designed for performance upgrades in high-speed digital systems.

Replacement Considerations

The datasheet lists MK2308S-1HLF as the lead-free equivalent for commercial temperature variants. For industrial temperature replacements, verify pin-compatible alternatives within the Renesas portfolio that maintain zero delay buffer functionality and similar skew specifications.
