Chronos can supply, install and support your telecom master clock solution, with a resilient timing network in an Ethernet environment using IEEE1588v2 (Precision Time Protocol or PTP) standard protocol and SyncE, utilising GNSS (GPS, GLONASS, Galileo, BeiDou).

Timing profiles supported include Telecom-2008, ITU-T G.8265.1, ITU-T G.8275.1, ITU-T G.8275.2, and ITU-T G.8273.4 APTS with enhanced automatic asymmetry compensation.

Applications include 5G TDD and LTE-A edge timing; fronthaul, middlehaul, and backhaul via fixed or wireless transport; small cells and indoor enhanced mobile coverage.

Whether the application requires TimeCesium, TimeProvider 4100 with or without GNSS, or an IGM edge deployment, Chronos can deliver the optimum telecom master clock solution for stability and supportability in your network.

The Chronos difference

Combining over 30 years’ sync and timing experience with Microchip’s comprehensive range of IEEE 1588 and SyncE solutions, we assist our customers with the planning, deployment and maintenance of telecom master clocks, utilising synchronisation infrastructure to deliver the highest level of performance from their synchronisation networks whether fixed, cable, 3G, 4G/LTE, LTE-Advanced or 5G wireless.


Mobile Networks

Deploying LTE-A and 5G TDD services adds increasingly stringent time and phase requirements at the edge of mobile networks. In addition to the parts per billion synchronisation required to maintain stable frequency in previous generations, LTE-A services and 5G demand sub-microsecond and even nanosecond timing performance in your network.

With timing now being just another service in your network, we have the design and delivery skills to ensure time and timing is delivered in a resilient and reliable way; using technologies such as Microchip’s patented APTS technology to ensure superb timing performance even under failure conditions.

GPS and GNSS alone are not adequate to deliver reliable time and phase in a supportable and scalable way; Chronos can deliver a robust and scalable timing system fit to deliver these microsecond and nanosecond services as your network and services evolve.

Fixed Networks

The move from deterministic transport technologies such as SDH/SONET to Ethernet poses a particular problem in fixed networks. The transport technologies themselves do not require stable frequency, time or phase synchronisation to operate, but services relying on this transport may well do so.

As part of a mobile carrier’s network this means the fixed network segment must adequately support whatever timing technologies the mobile edge requires; as a third-party carrier you may have an opportunity to supply timing services to mobile carriers but must at the very least ensure your fixed network service does not undermine the carriers’ timing strategies.

Chronos can deliver a resilient and reliable core timing platform to support the exacting requirements of LTE-A and 5G TDD mobile networks.

Small Cells and In-building coverage

The challenge for small cell deployment on time and phase performance are the same as those in the macro and fixed network but require lower cost solutions that are easily deployed. Chronos can deploy edge devices such as the IGM or “aggregation” sites using TimeProvider 4100, to deliver these services while being supported by a resilient core timing network deployed in the backhaul network.
