latest coverage of CDMA and TDMA systems, this is the only book in the wireless digital communications field which contains an in-depth analysis and description of practical R&D, design, and implementation sections, with an emphasis on the newest generations of modulation and spread spectrum systems...
The depth of the FIFO depends on the modulation frequency in the clock. The slower the modulation, the deeper the FIFO needs to be: When down spread-spectrum clocking (DOWN_LOW or DOWN_HIGH) is used, the output frequency is lower than the original clock frequency, which means that if no...
The chip is able to generate signals up to 1.27 GHz. The measured peak level reduction of the clock spectrum, at 750 MHz output frequency, is 20.5 dB with a 6% modulation depth. The power dissipation is 44 mW @ 1.27 GHz. 展开

A spread spectrum clock signal generator for spreading an input clock signal into an output clock signal includes a clock signal delay chain for delaying the input clock signal into a delay clock signal group having a plurality of delay clock signals, a modulation controller for outputting a count...
When spread spectrum modulation is applied to an echo-cancelled system, propagation delay of the link becomes important. Thus, according to embodiments, the algorithm implementing clock adjustment on the slave side is made aware of the cable length when setting its own clock and the clock is set...
A graphics controller uses spread-spectrum techniques to modulate the pixel clock over a range of frequencies, reducing the maximum intensity of EMI emissions. When the clock input to the graphics con
