Texas Instruments has introduced a wideband frequency synthesiser with integrated low phase-noise voltage-controlled oscillator. The device combines a low noise phase-locked loop (PLL) and a phase ...
An important task for a digital communications receiver is to remove any frequency/phase offsets that might exist between the transmitter and receiver oscillators. Designers typically implement a ...
Many RF systems, especially those related to the telecom market, need reference signals with accurate and stable frequencies. Single-chip PLLs (phase-lock loops), such as those that several IC ...
The performance of analogue phase-locked loops (PLLs) has steadily improved with operating frequencies extending to 8GHz and beyond. Recently, digital PLLs based on direct digital synthesis (DDS) have ...
Phase-locked-loop (PLL) frequency synthesizers are signal sources often employed in many types of electronic equipment. They show up as clock sources in high-frequency instruments and as local ...
The Texas Instruments LMX2581 phase-locked loop (PLL) frequency synthesizer integrates a voltage-controlled oscillator (VCO) that covers from 50 to 3760 MHz and offers perhaps the best phase-noise ...
[Kenneth Finnegan] put up a lengthy primer on PLLs (Phase-Locked Loops). We really enjoyed his presentation (even the part where he panders to Rigol for a free scope… sign us up for one of those too).
180TSMC_PFD_01 is a phase-frequency detector (PFD) forms a control signal for VCO tuning. PFD compares phases of a divided VCO signal and a divided reference oscillator signal and detects phase ... It ...
An important task for a digital communications receiver is to remove any frequency/phase offsets that might exist between the transmitter and receiver oscillators. Designers typically implement a ...
