Pre-emphasis apparatus, low voltage differential signaling transmitter including the same and pre-emphasis method |
摘要 |
A pre-emphasis apparatus of a LVDS transmitter includes a pre-emphasis signaling generation unit and a pre-emphasis current output unit. The pre-emphasis signal generation unit generates a pre-emphasis pulse signal based on N parallel data signals received from an external source and N-phase clock signals received from a phase locked loop, where N is an integer greater than 1. The pre-emphasis current output unit provides an additional current for a pre-emphasis operation to a current source of a LVDS driver in response to the pre-emphasis pulse signal generated by the pre-emphasis pulse signal generation unit. The pulse signal for pre-emphasis is generated based on the parallel data signals received from the external source and the multi-phase clock signals, which are output from the phase locked loop for performing a sampling of the parallel data signals.
