342MIPLF

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS342MIPLF is a field-programmable dual-output clock synthesizer from the VersaClock family, manufactured by Renesas Electronics Corporation (formerly IDT). It operates within a supply voltage range of 3.15V to 3.45V and supports maximum output frequencies up to 200MHz. The device utilizes two independently configurable Phase-Locked Loops (PLLs) with M/N multipliers (M=12048, N=11024) to generate frequencies between 250kHz and 200MHz. It features spread spectrum capability for EMI reduction and includes One-Time Programmable (OTP) ROM for configuration storage in an 8-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Dual-output clock synthesis using two independent PLLs
• Spread spectrum modulation for system EMI reduction
• Field programmability via OTP ROM using VersaClock software
• Power-down mode that tri-states outputs and disables PLLs

Clock Generators, PLLs, Frequency Synthesizers Applications

• Replacing multiple discrete crystals and oscillators to save board space
• Low-cost clock generation for general electronic systems
• Applications requiring specific frequency generation from standard fundamental mode crystals

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The ICS342MIPLF is listed as obsolete or end-of-life by major distributors such as DigiKey. Verification of current availability requires checking authorized channels or alternative packaging types. Designers should confirm RoHS compliance status and moisture sensitivity level (MSL 1) before procurement planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

This component is suitable for designs requiring dual LVCMOS outputs up to 200MHz with spread spectrum capabilities. It replaces fixed-frequency oscillators but requires external crystal/clock input. Configuration is achieved via OTP programming; factory-programmed custom versions are available for high-volume applications. Ensure the 8-SOIC package fits the target footprint.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The ICS342 belongs to the VersaClock family of clock generators. Renesas has indicated a transition of VersaClock products to SiTime, with support expected until the end of 2026. The part is functionally similar to other VersaClock synthesizers but is distinct from buffer drivers like the 524M series.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public documentation lists the 5P35021 (VersaClock 3S) as a potential substitute. Verify pin compatibility and programming requirements when considering alternatives due to the obsolescence of the ICS342.
