IEEE 1588 IP

Design IP

Overview

SmartDV’s IEEE 1588 Precision Time Protocol (PTP) IP is a silicon-proven solution engineered for applications requiring precise time synchronization across distributed systems. Compliant with IEEE 1588-2008 (PTPv2) and optionally supporting IEEE 1588-2019 (PTPv2.1), it ensures nanosecond-level accuracy for networking, industrial automation, telecom, and automotive applications.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. Its modular architecture supports hardware timestamping, multiple clock domains, and seamless integration with Ethernet MACs, enabling accurate and reliable synchronization in complex, real-time environments.

Benefits

Precise Time Synchronization – Implements IEEE 1588 Precision Time Protocol (PTP) with hardware-based timestamping for sub-microsecond accuracy across distributed systems
