ICS508MILFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS508MILFT is a clock generator IC from the ClockBlocks family, manufactured by Renesas Electronics Corporation. It converts PECL input signals to CMOS outputs with a maximum frequency of 250 MHz. The device operates on a single supply voltage ranging from 2.375 V to 5.5 V and supports an industrial temperature range of -40°C to +85°C. Packaged in an 8-SOIC (0.154" width) surface-mount package, it features separate VDD supplies for input and output buffers to facilitate voltage translation. The component has a 1:1 input-to-output ratio and includes an Output Enable pin for tri-stating the clock output.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Converts PECL input to CMOS output with frequencies up to 250 MHz
• Separate VDD supplies allow independent voltage levels for input and output buffers
• Industrial temperature rating (-40°C to +85°C)
• Tri-state output capability via dedicated Output Enable pin

Clock Generators, PLLs, Frequency Synthesizers Applications

• Clock generation systems requiring PECL to CMOS conversion
• Voltage translation between different logic families in timing circuits
• High-frequency digital system clock distribution

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The ICS508MILFT is listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life status updates. Designers should consider replacement components due to the discontinuation status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component only if PECL input and CMOS output compatibility is required within the 250 MHz limit. Ensure the design accommodates separate power supplies for the input buffer and output buffer to utilize the voltage translation feature. Verify that the 8-SOIC package fits the PCB layout constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The ICS508MILFT belongs to the IDT/Renesas ClockBlocks family of clock generators. It is specifically designed for cost-effective high-frequency clock generation from PECL sources. The 'M' suffix indicates the industrial temperature range, while 'ILFT' denotes the 8-SOIC package with tape-and-reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

As the ICS508MILFT is obsolete, verify specific replacement part numbers from Renesas or compatible manufacturers that offer PECL-to-CMOS conversion with similar electrical characteristics and package dimensions.
