ACS9528


The ACS9528 features two separate PTP master blocks, driven from a common timebase, and two independent SGMII Ethernet ports. Each master block can be associated with either SGMII port for maximum flexibility. The master blocks can be individually configured to support different operating parameters of PTP, such as layer 2 (Ethernet) or layer 3 (UDP/IP), different PTP domains and one or two-step operation. Each SGMII port has individually programmable Ethernet MAC and IP addresses. By associating both master blocks to a single SGMII port, both layer 2 and layer 3 master functionality can be provided on one port.

  • Complete dual IEEE1588-2008 master function in a single device

  • Ideal for applications such as:

            PTP grandmaster
