Abstract
A synchronization apparatus in a selective call receiver comprised of a digital variable bandwidth phase locked loop with means to simultaneously detect the synchronization code word, means to generate a binary code from a register representative of lock quality, means to increment or decrement the lock quality register, means to sum the lock quality binary code into a phase error register, whereby the polarity of the sum is controlled by a phase comparison of the a local clock with the received data, and whereby the under or over flow of the phase error register determines the direction of a phase adjustment to the local bit clock generator.
