84330CM-01LF

Clock Generators, PLLs, Frequency Synthesizers Overview

The 84330CM-01LF is a general-purpose, single-output high-frequency frequency synthesizer manufactured by Renesas Electronics. It features a fully integrated Phase-Locked Loop (PLL) that eliminates the need for external loop filter components. The device accepts a crystal oscillator input in the range of 10MHz to 25MHz and generates an output frequency ranging from 31.25MHz to 700MHz. The internal Voltage-Controlled Oscillator (VCO) operates within a frequency range of 250MHz to 700MHz. The output stage provides a differential 3.3V LVPECL signal. Programming of the M and N dividers is supported via parallel or serial interfaces during power-up.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized channels as counterfeit risks exist for legacy clock devices. Confirm RoHS compliance status and lead-free packaging specifications prior to integration. Check for Product Change Notices (PCN) regarding manufacturing site updates or material substitutions. Ensure supply chain stability given potential end-of-life status for older FemtoClock series parts.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single differential LVPECL output is required without external filtering complexity. Verify that the input crystal frequency falls between 10MHz and 25MHz. Ensure the target output frequency does not exceed 700MHz. Confirm that the 3.3V supply voltage aligns with system power rails. Consider alternative models if multiple outputs or different logic families are needed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the FemtoClock family of low-jitter clock synthesizers produced by Renesas Electronics. It is designed for applications demanding precise frequency generation from standard crystal references. The device simplifies board design by integrating the PLL loop filter internally, reducing component count and layout sensitivity compared to discrete PLL solutions.
