<p>PROBLEM TO BE SOLVED: To provide a bit synchronization circuit that can have no dead band phase, instantaneously establish synchronization, and can be in operation even at a high-speed bit rate of 10 Gb/s or over. SOLUTION: The bit synchronization circuit of this invention is characterized in that a phase and an amplitude of a data signal are compared with those of a reference clock signal to instantaneously establish bit synchronization, the circuit is configured with a simple logic, the bit synchronization is instantaneously established because of absence of a feedback loop, the phase of the data signal is analogically compared with the phase of the clock signal, and sampling and holding the result of the phase comparison receives no limitation of a preamble pattern.</p> |
