To ensure all VCO cores work in harmony, proper VCO calibration is required. The calibration is critical to VCO frequency selection and meaningful to the frequency switching time.

PLL lock time is an important metric in many synthesizer applications. Because the TRF3765 uses multiple VCOs and digitally switched capacitor banks to achieve extremely wideband …

What is a PLL Synthesizer? A. A frequency synthesizer allows the designer to generate a variety of output frequencies as multiples of a single reference frequency. The main application is in …

The power-management requirements for the main PLL blocks were discussed, and specifications were derived for the VCO and charge pump supplies. Analog Devices provides multiple design …

The ADF4401A is a fully integrated, system in package (SiP) translation loop (also known as an offset loop) module that includes a voltage controlled oscillator (VCO) and calibration phase …

3.1 To achieve reliable locking of the Reference PLL (REF_PLL) and the Synthesizer PLL (SPLL) whilst utilising their associated on-chip VCOs, an internal automatic calibration process may …

With an HMC PLL with integrated VCO (e.g. HMC1033) when using a high N counter value, say N > 4000 (such as when the PFD frequency is low), the PLL does not always function with VCO …

In a wide tuning-range fractional- N PLL frequency synthesizer, high-speed and high-precision automatic calibration is especially important for shortening the lock time and improving the …

Oct 18, 2004 · Abstract: The article discusses auto calibration of phase lock loops (PLLs), particularly when used as frequency synthesizers in fully integrated radios targeting future …
