METHOD FOR TRANSMITTING DATA FROM MULTIPLE CLOCK DOMAINS AND A DEVICE HAVING DATA TRANSMISSION CAPABILITIES

摘要

A method (600) that includes defining (610) a transmission schedule of a TDM data frame that includes multiple TDM time slots allocated for transmitting data over a TDM line; the method (600) is characterized by including: providing (615) a transmission clock signal having a transmission clock frequency to the TDM line, providing a first clock signal having a first clock frequency to data sources that belong to a first group of data sources and providing a second clock signal having a second clock frequency to data sources that belong to a second group of data sources; wherein the first clock frequency and the second clock frequency are higher than the transmission clock frequency; pre-fetching (620), to a first intermediate storage a data segment from a data source out of the first group of data sources in response to a fullness level of the first intermediate storage unit and to the transmission schedule; pre-fetching (630), to a second intermediate storage a data segment from a data source out of the second group of data sources in response to a fullness level of the first intermediate storage unit and to the transmission schedule; providing, (640), in response to the transmission schedule, a stabilized data segment from the first or the second intermediate storage units to a transmission storage unit and transmitting (650) the data segment from the transmission storage unit over the TDM line.
