IEEE™ 1588 PTP grandmaster clock for 4G and 5G: Page 2 of 2

Microsemi Corporation has launched its TimeProvider 4100, a highly flexible IEEE™ 1588 Precision Time Protocol (PTP) grandmaster clock designed to scale from the edge to the aggregation layers of both mobile infrastructure and access networks.

The TimeProvider family serves the mobile infrastructure market, which is expected by market research firm IHS Markit to be approximately $48 billion in 2018, with hardware expected to account for approximately 62 percent of the market. The TimeProvider family is designed to capitalize on growth opportunities related to 5G installations, beginning with trial installations in 2018, growing to a market size of $2.8 billion by 2021 according to the firm's "Mobile Infrastructure Intelligence Service – 3Q17 Market Tracker."

Importantly, the latest device's flexibility does not compromise its performance and feature set, and meets stringent precise timing requirements, including complying with primary reference time clock (PRTC) and the latest time and phase ITU-T and IEEE industry standards. It supports GNSS constellations including GPS, Beidou, Glonass and Galileo. Available upgrades include oscillator options for enhanced holdover performance and an internal expansion module which adds 16 E1/T1 BITS ports to the device. The TimeProvider 4100 also accepts PTP input with assisted partial timing support (APTS) to back up the GNSS signal in case of signal loss for high resiliency of the system by leveraging 1588v2 grandmasters already deployed at the core of the network.

TimeProvider 4100 can be managed through Microsemi's timing and synchronization management platform, TimePictra. In addition, for phase, service providers require more visibility about performance and health of the various network elements participating in the synchronization chain. TimeProvider provides advanced monitoring capabilities, especially for IEEE 1588v2 PTP for phase, and leverages a WebGUI to present results and calculations for easier interpretation.
