Microsemi has enabled cable TV and internet provider Stofa, based in Denmark, to successfully complete the first trial in Europe deploying a new type of architecture—Remote PHY (R-PHY)—based upon the DOCSIS® 3.1 standard in Europe. Using Microsemi’s TimeProvider 4100, a highly flexible IEEE™ 1588 Precision Time Protocol (PTP) grandmaster clock, to meet the stringent PTP synchronization requirements of the new Remote PHY architecture, Stofa thoroughly tested the device to ensure suitability for the cable industry’s deployments.
R-PHY technology enables more efficient use of the network media, enabling service speeds of up to 1Gbps. DOCSIS 3.1 specifies stringent synchronization requirements based on the IEEE™ 1588 v2 standard, whereby the cable modem termination system (CMTS) and the R-PHY devices act as IEEE-1588 v2 slaves with 1 millisecond phase alignment enabled via a IEEE-1588 v2 grandmaster provided by Microsemi.
