WebJan 25, 2024 · However, we had no direct control over the CPU clock, which also drove its hardware timers. Therefore, I invented a kind of "software PLL" to fill the gap. The basic idea is that we set up a hardware timer (call it T1) to produce the 5 ms interrupts we needed. Suppose the processor clock is nominally 50 MHz. WebManipulating the placement of the PLL loop filter bandwidth (LBW) shows how decreasing it too much has an effect in which VCO noise begins to dominate at small offsets (Figure 24) where the in-band PLL noise would in fact be lower, and increasing it too much means the in-band noise is dominating at offsets where the VCO noise would instead be significantly …
