342MPLFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 342MPLFT is a field-programmable dual-output clock synthesizer from the VersaClock series, housed in an 8-SOIC package. It generates output frequencies ranging from 250 kHz to 200 MHz using two independently configurable PLLs. The device operates on a supply voltage of 3.15V to 3.45V and supports LVCMOS outputs with a 1:2 input-to-output ratio. It features spread spectrum capability for EMI reduction and includes one-time programmable ROM for configuration storage.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is officially marked as End-of-Life (EOL) by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct distributor stock. Confirm RoHS compliance status and check for specific manufacturing date codes when sourcing replacement units.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for applications requiring dual independent clocks derived from a single reference. Ensure the design accommodates the 3.15V–3.45V supply range and LVCMOS output levels. Verify that the required frequency range falls within the 250 kHz to 200 MHz specification before finalizing the design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The 342MPLFT belongs to the ICS342 family of VersaClock synthesizers. It serves as a cost-effective alternative to discrete oscillators, reducing board space by integrating PLL functionality into a single 8-pin package. The device allows for custom frequency configurations through factory programming or user field programming.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers must evaluate pin-compatible alternatives or redesign for newer VersaClock generations if direct substitution is required.
