San Jose, Calif. - Arasan Chip Systems, Inc. has integrated support for IEEE 1588 Precision Time Protocol (PTP) into its Ethernet IP core. Mission critical environments such as factory automation systems, networking environments, manufacturing, test and measurement systems rely on IEEE 1588 to maintain precise timing synchronization in order to execute activities in real-time.
Arasan's Ethernet IP with IEEE 1588 enables these distributed systems to select a master clock and compensate for network delay and jitter while keeping the remainder (slave) clocks in tight synchronization with the master. While other clock synchronization schemes exist, IEEE 1588 PTP implemented over Ethernet offers a scalable, economical solution for clock synchronization across geographically distributed locations.
Wireline and wireless network operators can now use IP/Ethernet as the single backhaul network to carry both 2G/3G voice and IP/Ethernet packet traffic instead of using the hybrid two-network approach.
"While the ubiquity and maturity of Ethernet protocol make it a natural choice for data networks, the lack of deterministic frame delivery impedes its deployment in timing critical environments," said Somnath Viswanath, Product Marketing Manager at Arasan. "System designers can extend their LAN products to enable a single network that can support hard, real-time environments by using Arasan's Ethernet cores with IEEE 1588 PTP."
Arasan's Ethernet IP cores can parse all standard IEEE 1588 frames and has hardware time-stamping for both ingress and egress frames performed at the respective ports. The core implements accurate time monitoring and is capable of synchronizing with an external timer.
The IP also includes timers and event synchronization blocks to generate external events based on received PTP packets. The integration of this functionality improves the accuracy as well as reduces the BOM for supporting IEEE 1588 over an Ethernet infrastructure.
Arasan's comprehensive portfolio of Ethernet IP includes UNH certified Gigabit, Fast Ethernet Controllers and corresponding portable Ethernet Software Stacks for rapid integration into SoC and FPGA solutions.
