Bellcore GR-1288 defines different clock levels (Stratum) and their requirements for synchronization network clocks, reflecting varying levels of time accuracy for network performance. The Stratum 3 clock, in particular, requires stability for over 20 years in free-run mode, with a deviation not exceeding ±4.6ppm. Additionally, it must maintain a deviation within ±0.37ppm (±370ppb) during continuous operation exceeding 24 hours. Taitien Electronics' Stratum 3 TCXO provides an outstanding solution for addressing timing issues in communication systems. Not only does it comply with the quality assurance standards set by Bellcore, but it also offers exceptional frequency stability and phase noise performance to meet the demands of high-precision clocks. Whether your application involves mobile base stations, testing instruments, or other areas requiring high-precision clocks, choosing Taitien Electronics' oscillators brings unparalleled stability and reliability to your communication system.
