343MIPLFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 343MIPLFT is a VersaClock clock/frequency synthesizer IC 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 circuit with an input-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" width) and is designed for surface mount installation. It includes an internal PLL and functions as a frequency multiplier without division capabilities.

Clock Generators, PLLs, Frequency Synthesizers Applications

• General clock distribution in electronic systems requiring LVCMOS compatibility
• Frequency synthesis for digital circuits utilizing the VersaClock family architecture
• Industrial or commercial equipment operating within standard industrial temperature ranges

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component status carefully, as public records indicate the base part number 343MI may be End-of-Life (EOL). Confirm that the 'T' suffix denotes the specific tape-and-reel packaging variant distinct from the tube-packaged version. Ensure the supplier provides traceability documentation matching the Renesas manufacturing standards for this discontinued series.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed 1:3 frequency multiplication ratio is required with LVCMOS outputs. Verify that the system power supply strictly adheres to the 3.15V–3.45V specification. Consider the 8-SOIC footprint constraints during PCB layout. Note that this is a non-programmable fixed-function device; if dynamic reconfiguration is needed, a programmable alternative from the same family must be selected.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The 343MIPLFT belongs to the Renesas VersaClock family, specifically derived from the ICS343 product line. It serves as a specialized clock generator for applications needing simple fan-out and frequency multiplication. The part is often referenced under aliases such as ICS343MIPLF. It represents a legacy solution within Renesas's broader portfolio of timing devices.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public data indicates the base 343MI series has reached End-of-Life status. Direct replacement requires verifying pin-compatible alternatives from current Renesas VersaClock lines or generic 1:3 LVCMOS clock buffers. Validate that any substitute matches the 200MHz speed grade and 8-SOIC package dimensions.
