Lattice ORAN 1.1 solution stack is an ORAN reference design compliant to IEEE 1588-2019, ITU-T G8265.1 (Frequency Sync), ITU-T G8275.1 (Phase/time Sync with full network support), ITU-T G8275.2 (Phase/time Sync with partial network support Sync), and IEEE 802.1AS-gPTP (Time Sensitive Network) with built in security by mutual authentication.
The CertusPro-NX 10GbE PTP Mother Board offers 2x 10GE and 2x 1GE ports connected to SFP+ module cages, a Mezzanine board connector, SMA, and FMC connectors, GNSS and on-board timing sources as well as the ability to plug into a PCI-e server slot. This enables simple testing, demonstration, and developing new IEEE 1588 compliant secure synchronization applications.
The 1588 PTP Daughter Board support high-performance MEMS Jitter Attenuator, Clock Synchronizer (DPLL), Oven Controlled Crystal Oscillator (OCXO), Global Navigation Satellite System (GNSS) Module, 1PPS output on SMA and 1PPS+ToD input and output on RJ48 ports. The PTP Daughter Board is firmly plugged into the Mother Board and draws power from the Mother Board via the board to board connector.
PTP Profiles – The IEEE 1588v2 standard includes the concept of PTP profiles to describe the network parameters, allowed clock types, clock domain number, and others. The following profiles are supported by the Lattice ORAN solution stack.
