342MPLF

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 342MPLF is a field-programmable dual-output clock synthesizer from the VersaClock series, housed in an 8-SOIC package. It generates output frequencies up to 200 MHz using two independently configurable PLLs with M/N multiplier capabilities (M=12048, N=11024). The device operates on a 3.15V to 3.45V supply and supports LVCMOS outputs. It features spread spectrum capability for EMI reduction and includes one-time programmable ROM for configuration storage.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The 342MPLF is officially listed as obsolete by Renesas Electronics Corporation. Verification of availability should focus on distributor surplus stock or alternative packaging types if documented. Designers must confirm end-of-life status and transition plans before procurement attempts.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

This component requires external crystal or clock input and utilizes ICS VersaClock software for PLL configuration. It is suitable for designs needing dual LVCMOS outputs within a narrow 3.3V voltage range. Consider the 8-SOIC package dimensions and 0°C to 70°C operating temperature range during integration.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The 342MPLF belongs to the VersaClock family of clock synthesizers. It serves as a low-cost solution for generating precise clock signals from standard fundamental mode crystals. The device integrates programmability features to replace discrete oscillator components in general-purpose system control applications.
