Sonoma D12(GPS)

The Sonoma is a high-performance Time Server that provides a secure and reliable source of network time inside your firewall.EndRun Technologies has been designing network time servers since the 1990s, and the Sonoma is the 3rd generation in that standard-setting line. It can serve accurate time to any system running an NTP or SNTP client. With dual gigabit ports and a fast microprocessor for high-capacity throughput (7,500 NTP requests/second), the Sonoma can support hundreds of thousands of NTP clients on your network(s). And with an optional upgrade, it can operate as a Precision Time Protocol (PTP) Grandmaster Clock with hardware timestamping on both gigabit ports.


You can easily manage the Sonoma using either of the network ports, the RS-232 serial port or the vibrant display and keypad. A secure Web Interface (HTTPS) is also provided for status monitoring using your Internet browser.


PTP/IEEE-1588 Grandmaster Clock Option

The Sonoma can be configured as a PTP Grandmaster Clock by enabling the PTP/IEEE-1588 option on one or both of the gigabit ports. Using both ports enables one Grandmaster to service two independent PTP sub-domains.


Each Sonoma is shipped from the factory ready hardware-based PTP timestamping with 8-nanosecond resolution. You can purchse the option eithe rbefore or after Sonoma is shipped from the factory. Hardware timestamping delivers the level of performance that is required in today's high-speed, low-latency systems.


Reliable Hardware Design

The superior reliability of the Sonoma is the result of our very highly-integrated, efficient hardware design that is unique to our products. This design achieves an estimated MTBF of over 25 years (16 years with Rubidium). We do not use general-purpose CPU boards (sometimes referred to as single-board computers (SBC)). Instead, by using the latest semiconductor technologies found in tablet computers, we have achieved an optimal combination of reliability, performance and power consumption. The CPU is a highly-integrated System-on-Chip (SoC) and the circuitry around it is assembled with 100% soldered-down memory components rather than consumer-grade, plug-in, FLASH or DRAM memory modules. The chassis is sealed to keep air currents and dust off sensitive frequency control components. No fans are needed, due to the efficiency of the design. This built-in reliability is combined with a production process which integrates strigent quality assurance inspections and rigorous performance verification.
