Pll Design Assistant 1.0

Pll Design Assistant is a focused tool for designing and analyzing phase‑locked loops used in RF, clocking, and mixed‑signal systems. It helps you plan frequencies, choose loop‑filter topologies, and size components while visualizing key performance and stability metrics. With clear calculators and plots, you can quickly iterate toward a stable, low‑jitter design and document your results for review.

Key capabilities:

• Supports integer‑N and fractional‑N synthesizer planning
• Loop‑filter synthesis (common 2nd–3rd‑order passive/active topologies) with component calculation
• Stability analysis: loop bandwidth, phase margin, and peaking
• Time‑domain metrics: lock time and settling behavior
• Noise and jitter budgeting with reference, VCO, and PFD/charge‑pump contributions
• Visualizations: open‑loop gain, closed‑loop response, step response, and noise transfer
• What‑if sweeps and sensitivity checks for component tolerances
• Unit‑aware inputs, guardrails, and design rule checks
• Exportable plots and concise design summaries

Ideal for RF engineers, clocking specialists, and students who need to move from frequency plan to verified PLL design with confidence.
