The superior performance of ClockMatrix devices makes them ideal for a broad range of networking, broadcast video, optical transport network (OTN) and industrial automation systems that require critical timing performance for clock generation, frequency translation, jitter attenuation and phase alignment.
First, the problem of the direct Tx-to-Rx leakage through antennas or isolators can be solved due to frequency translation, removing the serious drawback of the AMCW radar system.
If X(f) denote the Fourier transform of x(t), then x(t)exp(j2pf0t) denote the Fourier transform ofX f f0 using frequency translation property.
The phase quadrature double-sideband frequency translation technique has been proposed to transport MIMO radio signals over single optical fiber [9].
The devices' high level of integration and low jitter eliminates the need for separate frequency translation, redundancy management, and jitter attenuation devices empowering system designers to save cost and board area by consolidating those functions into a single device.
In radio frequency (RF) receivers, mixers are important components which provide the frequency translation from RF signals to the intermediate frequency (IF) signals called "down-convert".
Then, after frequency translation and decimation, the data is stored as complex I&Q samples to the digitizer's memory.
It is used for frequency translation with the voltage-controlled oscillator (VCO) [1-3] and designed to be controllable to synthesize the desired output frequencies [4] or synchronize the clock signals [5,6].
The main goal of the mixer stage is to obtain the needed frequency translation of the input signal.
Applications for the CVS575S-500, according to the Fort Myers, FL-based frequency control parts manufacturer, include frequency translation, test and measurement, and others.
These VCOs have much reduced AM noise levels at the cost of increased harmonic levels and increased phase noise due to frequency translation. In this case, the measurement can be called a 'phase noise' measurement.
