ICS501MT

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS501MT is a LOCO™ PLL clock multiplier manufactured by Integrated Device Technology (IDT), now part of Renesas Electronics. It generates high-frequency clock outputs up to 160 MHz from lower frequency crystal or clock inputs using Phase-Locked Loop techniques. The device features zero ppm multiplication error and extremely low jitter of 25 ps (one sigma). It operates at 3.3 V or 5.0 V with an operating temperature range of 0°C to +70°C. Packaged in an 8-pin SOIC, it includes nine selectable multiplication factors accessible via S1/S0 pins and provides tri-state output capability through an OE pin for board-level testing.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer origin as IDT/Renesas and confirm the specific suffix 'MT' indicates tape and reel packaging for the commercial temperature grade. Ensure RoHS compliance status matches project requirements, noting that non-green parts have reached end-of-life. Cross-reference the datasheet revision Q for accurate electrical specifications before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the ICS501MT when a cost-effective PLL solution is needed to replace crystal oscillators. Choose this component if the application requires zero ppm multiplication error and low jitter performance. Verify that the required output frequency falls within the supported range for the chosen supply voltage (up to 160 MHz at 5V, up to 100 MHz at 3.3V). Ensure the input source matches either the crystal or clock input specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The ICS501 is part of the LOCO™ (Low Cost Oscillator) family designed to replace traditional crystal oscillators. The 'MT' suffix specifically denotes the tape and reel packaging variant for the commercial temperature grade (0°C to +70°C) in an 8-pin SOIC package. This series is intended for general-purpose clock generation where cost and performance balance are critical.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers include ICS501M, ICS501MI, ICS501MLF, and ICS501MILF. These variants share identical functionality but differ in packaging (tube vs. tape/reel), temperature grade (commercial vs. industrial), and RoHS compliance status.
