Title:
BIPHASE CODE SIGNAL IDENTIFYING DEVICE
Document Type and Number:
Japanese Patent JP3462084
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely provide phase synchronism, even if there is a phase difference between an input biphase signal and a clock signal for identifying this signal.
SOLUTION: This signal identifying device is provided with a clock generating part 23 for generating a first clock signal CK1 synchronizing its phase with one symbol block of the biphase signal and a second clock signal CK2, having a prescribed phase different from that of the clock signal, first synchronizing pattern detecting part 21 for detecting a prescribed synchronizing pattern from data sampling the biphase signal with the clock signal CK1, a second synchronizing pattern detecting part 22 for detecting the synchronizing pattern from data sampling the biphase signal with the clock signal CK2, and initialization control part 30 for initializing the clock generation phase of the clock generating part 23 by detecting the synchronizing pattern through the synchronizing pattern detecting part 21 or 22.
