ICS574MT

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS574MT is a zero delay buffer IC manufactured by Renesas Electronics Corporation, originally developed by IDT. It utilizes a proprietary low jitter Phase Locked Loop (PLL) to provide four low skew outputs at speeds up to 160 MHz at 3.3 V. The device features full CMOS outputs with 18 mA drive capability and operates on a supply voltage ranging from 3.0 V to 5.5 V. Packaged in an 8-pin SOIC, it supports industrial temperature ranges of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero input-to-output delay alignment when feedback pin connects directly to an output
• Output-to-output skew less than 150 ps under equal loading conditions
• Supports Spread Smart technology for accurate tracking of spread spectrum clocks
• Full CMOS outputs providing 18 mA drive capability at TTL levels

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed clock distribution networks
• System synchronization requiring precise edge alignment
• Applications utilizing spread spectrum clock generators

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized channels as the product line has undergone manufacturer transitions. Confirm RoHS compliance status, noting that non-green parts faced end-of-life directives. Ensure the specific suffix matches the required temperature range and packaging format before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the ICS574MT variant specifically for tape and reel shipping configurations. Choose between standard commercial or industrial temperature ratings based on environmental requirements. Ensure the design accommodates the 3.0 V to 5.5 V operating voltage and includes necessary decoupling capacitors near power pins.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the ICS574 family of zero delay buffers. The 'MT' suffix indicates a tape and reel packaging option, distinct from tube-packaged variants like the MI. The device integrates PLL functionality to eliminate propagation delay between the input clock and the four buffered outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other ICS574 variants such as the ICS574MI for tube packaging or lead-free versions like the ICS574MILFT. Verify package compatibility and temperature specifications when selecting alternative part numbers within the same family.
