843034CYLF

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 843034CYLF is a high-frequency clock synthesizer and jitter cleaner belonging to the FemtoClock family. It features a fully integrated Phase-Locked Loop (PLL) requiring no external loop filter components. The device accepts a crystal oscillator input within the 10MHz to 25MHz range and generates a single differential LVPECL output. The Voltage Controlled Oscillator (VCO) operates in the 250MHz to 700MHz range, allowing for flexible frequency synthesis. Configuration of the M and N dividers is supported via parallel or serial interfaces during power-up.
