343MIPLF

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 343MIPLF is a VersaClock clock/frequency synthesizer integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.15V to 3.45V and supports a maximum frequency of 200MHz. The device features one internal circuit with an input ratio-to-output ratio of 1:3. It accepts clock or crystal inputs and provides LVCMOS outputs. The component is housed in an 8-SOIC package (0.154 inch width) designed for surface mount installation. It includes an internal PLL and functions as a frequency multiplier without division capabilities.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The 343MIPLF is listed with a product status of End-of-Life (EOL). A Product Change Notification dated April 26, 2018, confirms the discontinuation of this device. Verification of current availability should focus on surplus distributors or alternative packaging options if applicable, noting that standard manufacturing has ceased.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Designers requiring this specific part number must account for its EOL status. When selecting a replacement, ensure compatibility with the 3.15V-3.45V supply voltage and LVCMOS output requirements. Verify that the substitute component supports the necessary 1:3 frequency multiplication ratio and fits within the 200MHz operational limit while maintaining the 8-SOIC form factor or adapting to a compatible footprint.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the VersaClock series of clock generators and frequency synthesizers. It is identified by the base part number 343MI. The suffix 'LF' indicates lead-free compliance, and 'P' denotes the tube packaging type. It is distinct from other Renesas timing devices by its specific 1:3 ratio and LVCMOS output configuration.

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 should consult Renesas for recommended next-generation alternatives or verify cross-compatibility with similar VersaClock family members that offer updated supply chains.
