GPS Time Distribution System (ENTA-R) Features • Versatile GPS Master Clock with Dual External GPS reference inputs • Dual 10/100BaseT Network interface with Network Time Protocol (NTP) • Multiple Have Quick Time Code Outputs (single ended and differential) • Multiple 1PPS outputs (single ended and differential) • High Stability Ovenized oscillator is standard • Ruggedized for Shipboard Usage • Hot-swappable Dual Redundant Power-Supplies Introducing the ENTA-R, a ruggedized version of Brandywine’s popular ENTA II, this unit is capable of delivering HaveQuick + 1PPS to a multitude of outputs. The ENTA-R is a full function Master Clock that is designed to provide a full suite of Have Quick time code and 1PPS outputs, as well as NTP, fully compliant with NENA requirements for a Master Clock. The ENTA-R provides four single-ended outputs that are either Have Quick or 1 PPS, as well as 12 differential outputs via RS422. The unit uses dual hot-swappable power supplies for high-reliability operation. A built-in web server provides user-friendly controls for configuring the unit. All outputs include signal level monitors to enable rapid fault-detection and isolation.
