14 years agoClock recovery from signle 125MHz pulses with PLL
Hi, I have a circuit that uses one PLL to recover data and clock from a single bitstream. This PLL is fed with 125 MHz clock, on it's output there is 375 MHz clock (which is used for the circuity ...

14 years agoI mean if you generate clock at 41.2KHz as such from inversion then it is a clock that is generated by gating as opposed to PLL. There is nothing wrong with this generation but then I will avoid using it as clock for edge triggering those registers. This means I will use your system clock(125Mhz) to trigger edges and use sync itself as clock enable on those registers. So I don't need to convert sync to clock in the first place.
