ICS525-01RI

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS525-01RI is a user-configurable clock generator from the OSCaR family, designed to replace crystal oscillators. It accepts an input frequency of 5–27 MHz (crystal) or 2–50 MHz (clock) and generates output frequencies up to 160 MHz at 5V or 140 MHz at 3.3V in the industrial temperature range (-40°C to +85°C). The device uses hardware-selectable dividers (Reference, VCO, Output) without software. It features low jitter (±140 ps absolute), CMOS outputs, and operates on a 3.0V to 5.5V supply. Packaged in a 28-pin SSOP.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Hardware-configurable via R, V, and S pins to generate specific output frequencies
• Industrial temperature range: -40°C to +85°C
• Low jitter performance with ±140 ps absolute clock period jitter
• Supports crystal inputs (5-27 MHz) or external clock inputs (2-50 MHz)

Clock Generators, PLLs, Frequency Synthesizers Applications

• Oscillator replacement in embedded systems
• Clock generation for digital logic and microcontrollers
• Frequency synthesis for communication interfaces

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the component matches the Renesas/IDT specification for the ICS525-01RI variant. Confirm the package is 28-pin SSOP and the temperature grade is Industrial (-40°C to +85°C). Check RoHS compliance status as non-green parts have reached End-of-Life.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed-frequency oscillator replacement is needed without programmability. Ensure the required output frequency falls within the limits defined by the selected Output Divider (OD) setting. Verify input source compatibility (crystal vs. clock mode).

Clock Generators, PLLs, Frequency Synthesizers Part Context

The ICS525-01RI belongs to the OSCaR (OSCillator Replacement) series by Integrated Device Technology (now Renesas). It is the industrial-grade version of the ICS525-01, distinguished by its wider operating temperature range compared to commercial variants.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

For applications requiring defined input-to-output timing relationships, consider the ICS527 series instead. For serial interface configuration, the ICS307 is an alternative.
