$960, GPS-disciplined, 10-MHz oscillator offers one part per trillion drift per day

Jackson Labs has announced the availability of Fury, a 10-MHz GPSDO (global-positioning system-disciplined oscillator) that requires no calibration, delivers greater stability than typical rubidium-clock references, and meets the stability requirements of a Stratum 1 frequency standard.
The unit offers less than 10–12, or one part per trillion, frequency drift per day; 4.5W power consumption; a phase-noise floor of –155 dBc/Hz, and extremely low spurs and jitter. The device generates a one-pulse-per-second output, phase-synchronized to UTC (Universal Time-Coordinated) and adjustable to UTC in 1-nsec steps. You can control the unit through an RS-232 port using industry-standard SCPI commands (Standard Commands for Programmable Instruments). The device provides SNTP (Simple Network Time Protocol) timing through its optional GPSCon software.
The manufacturer’s co-founder and president, Said Jackson, says that Fury has generated excitement not just because of its high performance, but also because of its competitive price: “The devices’ exceptional performance, low cost, and calibration-free operation have enabled our customers to use the PCB [printed-circuit-board] version as a frequency reference within OEM products and the fully enclosed modular version to synchronize groups of laboratory instruments.” The company is currently shipping the units. The PCB version is priced at $960 (one) and $750 (20 to 99), with lower prices for larger quantities.
