What is PTP Hardware Assist? Precision Time Protocol (PTP), defined by IEEE 1588, is the standard for synchronizing clocks across a packet network. In mobile networks—especially 5G—time alignment must be accurate to within ±1.5µs (or even ±130ns for some TDD configurations). Standard software-based PTP can struggle with packet delay variation (PDV), asymmetric paths, and high CPU loads.
