Renesas Electronics Corporation Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers 84021AYLFT

The 84021AYLFT is a high-frequency synthesizer designed for general-purpose applications, capable of converting crystal inputs to LVCMOS/LVTTL outputs. It operates with a voltage-controlled oscillator (VCO) frequency range of 620MHz to 780MHz, and the output frequency can be programmed between 103.3MHz and 260MHz. The device supports both selectable crystal oscillator and test clock inputs, allowing flexibility in reference source selection. This synthesizer features a fully integrated phase-locked loop (PLL) that requires no external components for loop bandwidth setting. It can be programmed via a serial or parallel interface, enabling easy configuration of the M and N dividers. The device exhibits low RMS period jitter of 14.7ps and phase jitter of 2.61ps at specific frequencies, ensuring stable output performance. The 84021AYLFT operates within a temperature range of 0¬8C to 70¬8C and is available in a lead-free 32-lead LQFP package. It is suitable for applications requiring precise frequency generation and can be utilized in various electronic systems where reliable clock signals are essential.
