Our design uses a HMC833 in integer mode. Our clock reference is 112MHz. We'd like to set the R value to 1 and run the internal PD frequency at 112MHz to reduce some spurious problems we're having. According to the HMC833 datasheet, a PD frequency up to 125 MHz is supported in integer mode. However, when we set the R value to 1, we cannot get the PLL to lock. Is there some trick to getting this to work?
