Apparatus for synchronizing clock using source synchronous clock in optical transmission system |
摘要 |
An apparatus for synchronizing a clock using a source synchronous clock is disclosed. The apparatus includes: channel receivers for receiving a source synchronous channel; divider for dividing the source synchronous clock to a low frequency clock; selectors for selecting one of the divided source synchronous clock and a system clock as a reference clock; detectors for generating a phase difference signal; phase difference signal selectors for selecting a phase difference signal from the detectors and a phase difference signal from an internal logic; and voltage oscillators for transmitting a clock synchronized to a source synchronous channel to the external optical transmission system by generating a predetermined synchronous frequency according to the selected phase difference signal.
