Abstract :
The proposed PLL realizes a fast and wide-ranging pull-in, and a stable locked condition by controlling a frequency difference detector and a PLL core with a dual loop constants in three modes. Simulations of the PLL designed with an 0.8 μm bipolar devices and experiments using a PLL-IC together with PLAs demonstrated the features; a short pull-in time comparable to SAW filters even for 63 bit PRBS NRZ inputs, low output jitter and no slowly-recovering phase error
