OSA 5422

Oscilloquartz OSA 5422 OCXO Stratum 3E, L1 Multi-GNSS Timing and Synchronization Platform

The Oscilloquartz OSA 5422 is a high-precision, multi-technology timing and synchronization platform designed for mission-critical networks requiring accurate, resilient and scalable synchronization. It combines IEEE 1588 PTP, NTP, SyncE, GNSS and physical timing interfaces in a compact 1U platform suitable for telecom, defense, utilities, broadcast, data center and other critical infrastructure applications.

This configuration features a Stratum 3E OCXO oscillator and L1 multi-constellation GNSS receiver. The OSA 5422 can operate as a PTP Grandmaster, Boundary Clock, Slave, NTP server and synchronization distribution platform. It also supports extensive physical timing interfaces, including BITS, PPS, Clock and PPS+ToD.

Multi-Constellation GNSS Timing

The integrated GNSS receiver provides a highly accurate UTC-traceable timing reference. The standard single-band implementation supports multiple satellite constellations and includes configurable signal-quality parameters, antenna cable-delay compensation and jamming and spoofing detection.

The OSA 5422 platform can also support optional multiband GNSS configurations for enhanced accuracy and resilience.

PTP Synchronization

The OSA 5422 supports a broad range of PTP profiles, making it suitable for multiple industries and network architectures.

Supported capabilities include:

• ITU-T G.8265.1 frequency delivery
• ITU-T G.8275.1 full timing support
• ITU-T G.8275.2 assisted partial timing support
• IEEE 1588 default profiles
• Enterprise PTP
• Power and utility profiles
• SMPTE ST 2059-2
• AES67
• IPv4 and IPv6
• Multiple PTP profiles operating simultaneously
• 1-step and 2-step operation
• Grandmaster, Boundary Clock and Slave operation

High-Performance NTP

The OSA 5422 provides high-capacity NTP timing distribution with hardware timestamping and can operate as a Stratum 1 NTP server when locked to GNSS.

NTP functionality includes:

• NTP v1, v2, v3 and v4
• SNTP
• IPv4 and IPv6
• NTP unicast, multicast and broadcast
• NTP peering
• PTP-to-NTP conversion
• Hardware timestamping
• Network Time Security, NTS, RFC 8915
• Authentication support
• Up to 500,000 NTP responder transactions per second without authentication

Assured and Resilient Timing

The OSA 5422 is designed for applications where loss or manipulation of GNSS cannot be allowed to disrupt network synchronization.

The platform supports multiple backup timing references, including:

• PTP
• SyncE
• PPS+ToD
• BITS
• Clock inputs
• Local oscillator
• Optional Iridium STL
• Optional M-Code

It can automatically switch timing references when interference, jamming or spoofing is detected.

Optional Iridium STL Resiliency

An optional Iridium Satellite Time and Location, STL receiver provides authenticated timing from low-earth-orbit satellites and creates a timing source independent of GNSS.

STL supports indoor and outdoor antenna deployments and provides timing accuracy within ±100 ns from UTC, 1 sigma, with an outdoor antenna. Its high-power LEO signal and authenticated architecture provide additional resilience against interference and signal manipulation.

Advanced Timing Options

Depending on configuration and licensing, the OSA 5422 platform also supports:

• White Rabbit PTP for sub-nanosecond Ethernet synchronization
• ePRTC, PRTC-A, PRTC-B and cnPRTC applications
• Multisource ePRTC combining up to five timing references
• Enhanced holdover algorithms
• Optional high-quality OCXO, DOCXO and Rubidium oscillator variants
• IRIG / Time Code
• Audio / Video synchronization
• Composite Clock
• Low Phase Noise 10 MHz outputs
• M-Code
• Additional Ethernet, PPS, Clock and BITS interfaces
