  • ADIsimPLL™- Version 3.43
    ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
  • ADIsimRF
    ADI’s ADIsimRF design tool provides calculations for the most important parameters within the RF signal chain, including cascaded gain, noise figure, IP3, P1dB, and total power consumption.

  • PLL Register Configuration Assistants
    These tools will generate the hex code values needed to configure the registers of the AD41xx and ADF42xx PLLs. They will also help determine the the values of the counters needed to obtain a certain output frequency given a reference clock.

  • Fundamentals of Frequency Synthesis, Part 1: Phased Locked Loops
    The first of a two-part series on frequency synthesis, with an introduction to Phased Locked Loops. This webcast looks at the need for frequency generation, the techniques from the past present and future, and how to assess the performance of a frequency synthesis, and real world applications. Particular attention will be focused on Phase Locked Loops (PLL's) as frequency synthesizers.
  • Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
    This month we conclude our two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.
