Phase-locked loop (PLL) frequency synthesizers are electronic devices that produce frequencies coherent to a reference frequency. Search by Specification | Learn More about PLL Frequency Synthesizers
IC phase-locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator. Learn More about Phase-locked Loops (PLLs)
RF phase detectors and comparators are circuits or instruments that provide a DC output voltage proportional to the difference in phase between two RF signals. Search by Specification | Learn More about RF Phase Detectors and Comparators
Quadrature phase shift keying (QPSK) modulators and binary phase shift keying (BPSK) modulators are used to change certain characteristics (amplitude, frequency or phase) of a carrier signal in order to transmit information. The changes in the parameter(s) of the carrier are made in accordance with an information-bearing signal (modulation signal). Search by Specification | Learn More about QPSK Modulators and BPSK Modulators
Frequency-to-voltage converters accept a signal and convert its frequency to a corresponding analog voltage level. Search by Specification | Learn More about Frequency-to-Voltage Converters
RF phase shifters are twin-ported devices that alter the phase of an output signal in response to an external signal. Search by Specification | Learn More about RF Phase Shifters
I/Q modulators and I/Q demodulators change the amplitude, frequency, or phase of a carrier signal in order to transmit information. I/Q modulators split an incoming data stream into its in-phase (I) and quadrature (Q) components, mix the resulting signals with local oscillators that are 90º apart in phase, and then combine the outputs vectorially in a 0º mixer. Search by Specification | Learn More about I/Q Modulators and I/Q Demodulators
Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement). Search by Specification | Learn More about Industrial Liquid Handling Pumps

In addition, PLLs and DLLs provide greater control over the clock frequencies used... Search by Specification | Learn More about Complex Programmable Logic Devices (CPLD)
...synthesizers feature a mix-filter-divide architecture and are used in some older electronic equipment. DDS frequency synthesizers create arbitrary waveforms digitally, from a single fixed-source frequency. Indirect or phase-locked loop (PLL... Search by Specification | Learn More about Frequency Synthesizers
Digital signal processors (DSPs) are specialized microprocessors designed specifically for digital signal processing, usually in real-time. DSPs can also be used to perform general-purpose computations, but are not optimized for this function. Search by Specification | Learn More about Digital Signal Processors (DSP)
Microprocessor chips (MPU) are silicon devices that serve as the central processing unit (CPU) in computers. They contain thousands of electronic components and use a collection of machine instructions to perform mathematical operations and move data from one memory location to another. Search by Specification | Learn More about Microprocessor Chips (MPU)
...voltages, invert voltages, or generate arbitrary voltages. In some products, a charge pump circuit can provide efficiencies as high as 90 to 95%. A charge pump PLL (CPPLL) circuit can be sized to satisfy performance requirements. Important... Learn More about Charge Pumps
