343MPLFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas Electronics Corporation 343MPLFT is a field-programmable clock synthesizer belonging to the VersaClock series. It operates within a supply voltage range of 3.15V to 3.45V and supports maximum frequencies up to 200MHz. The device features one circuit with an input-to-output ratio of 1:3, utilizing LVCMOS outputs. It accepts clock or crystal inputs without differential signaling capabilities. Designed for surface mount installation, it is housed in an 8-SOIC package (0.154 inch width) and functions within an operating temperature range of 0°C to 70°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The 343MPLFT component is identified as obsolete with a product status of End-of-Life (EOL). A Product Change Notification dated March 1, 2019, confirms this discontinuation. Verification of current availability requires checking authorized distributors for remaining stock or alternative packaging options, as standard manufacturing has ceased.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Designers should consider the 343MPLFT's specific 3.15V to 3.45V supply requirement and LVCMOS output levels when integrating into existing circuits. The 1:3 fan-out capability must align with system clock distribution needs. Due to the EOL status, replacement strategies involving pin-compatible or functionally equivalent active components are recommended for new designs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the ICS343 family of VersaClock synthesizers. The 'T' suffix typically denotes tape and reel packaging, while 'LF' indicates lead-free compliance. The base model ICS341 shares similar electrical characteristics but differs in having a 1:1 input-to-output ratio compared to the 1:3 ratio of the 343MPLFT.
