PLL and Votage regulator
I am using MC145170 PLL frequency synthesizer for a receiver design that uses MAX883 voltahe regulator. The problem is that I am experiencing glitches at the demodulated output. Could it be the voltage regulator noise that is cauing the problem.
MAX883 data sheet says that the regulator introduces 250 micro volt RMS output noise. I am using the PLL at 61 MHz for a freqency range of 0.98 MHz with 50 channels (20KHz spacing).
