Data receiving device for reproducing a received symbol from a received data signal |
摘要 |
A data receiving device for reproducing a received symbol from a received data signal, includes a timing recovery circuit for controlling a phase of sampling the received data signal, by using pre-cursor information, the timing recovery circuit produces sampling phase control information by eliminating a high frequency component for the pre-cursor information, accumulating eliminated output, comparing accumulated output with a positive or a negative threshold value and subtracting the threshold value from compared output. The data receiving device further includes a masking circuit for masking the sampling phase control information when no-signal data or frame is detected in the received data signal.
