601R-25ILF

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS601R-25ILF is a clock/frequency synthesizer integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.97V to 3.63V and supports frequencies up to 156MHz. The device features a 1:5 input-to-output ratio with CMOS outputs and includes both divider and multiplier capabilities via an internal Phase-Locked Loop (PLL). It is housed in a 20-SSOP package with a width of 3.90mm and functions across an industrial temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Integrated PLL-based clock frequency synthesizer with 1:5 output ratio
• CMOS output logic compatible with standard digital interfaces
• Supports frequency division and multiplication for flexible clock generation
• Operates on a single 3.3V nominal supply (2.97V–3.63V)

Clock Generators, PLLs, Frequency Synthesizers Applications

• System clock distribution in embedded electronics
• Replacing multiple discrete crystal oscillators to reduce board space
• EMI reduction through spread spectrum modulation techniques

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify RoHS compliance status as the specific ICS601R-25IT variant listed in source data indicates non-compliance. Confirm current production status, as related models are marked obsolete. Ensure the ILF suffix corresponds to lead-free packaging requirements if applicable to the target assembly process.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-ratio 1:5 clock synthesis solution is required without programmable registers. Verify that the 156MHz maximum frequency meets system timing requirements. Ensure the 20-SSOP footprint aligns with the PCB layout constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the ICS601 family of VersaClock synthesizers. It serves as a field-programmable or factory-programmed alternative to multiple discrete oscillators, designed to simplify clock tree design in consumer and industrial applications.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other ICS601 variants with compatible pinouts and electrical specifications. Verify package compatibility (20-SSOP) and voltage ranges before substitution.
