WebIntroduction Satellite set-top boxes (STBs) and television receivers contain a number of chips that require high-speed clocks. If the video decoder chip does not have an external clock drive—and many newer devices do not—a clock must be indirectly generated for any audio components that require it. This article shows how a phase-locked loop (PLL) can … WebMar 3, 2014 · The relation between the master clock frequency (fMCLK), the OSCM frequency (fOSCM) and the PWM frequency (fchop) is shown as follows: fOSCM = 1/20 ×fMCLK . fchop = 1/100 ×fMCLK . When Rosc=51kΩ, the master clock=4MHz, OSCM=200kHz, the frequency of PWM(fchop)=40kHz. 6-1. Current Waveform and …

Why? Because, for generating signal of Fmclk/2 frequency, DDS reads from the sin lookup table only two samples - one from positive and one from negative part. In case of AD9834 there are overall of 2^12=4096 samples in lookup table. how to setup remind
