Oscilloquartz SA / Rue des Brévards 16 / CH-2002 Neuchâtel Switzerland / Tel.+41(0)32 722 55 55 / Fax+41(0)32 722 55 56 osa@oscilloquartz.com / www.oscilloquartz.com GPS-based High Precision Clocks providing very High Stability and Accurate Frequency and Phase to the host system OSA 4500 OEM Clocks The OSA 4500 provides higher grade synchronization at minimal cost and minimal space. Based on the high performance Double Oven Oscillator OSA 8663, up to four 1 PPS and four 10 MHz outputs deliver time and frequency at a high level of accuracy and stability. Enhanced with its Aging and Temperature Drift Compensation (ATDC) system, the OSA 4500 becomes the most stable GPS quartz clock ever seen in holdover mode, especially in large temperature variations environment and harsh conditions. Numerous types of integration can be accommodated thanks to the OSA 4500 versatility, to easily adapting any integration into base stations, broadcast stations and such equipment, as an OEM timing clock solution. The OSA 4500 time and frequency is derived from the Global Positioning System (GPS). Up to 12 satellites can be tracked and a “position fix” mode is automatically trigged to reach higher stability. When no valid GPS reference input is available, the OSA 4500 enters in holdover mode and holds its output frequencies to supply long hours of frequency and phase accuracies. With ATDC system implemented, the OSA 4500 provides superior holdover stability, reaching phase variations lower than 5ìs per day. A comprehensive command set via RS232 serial line is available for the OSA 4500 management, allowing alarm reporting and full equipment control. The OSA 4500 is also very easy to integrate, highly reliable and totally maintenance-free. Highlights .. High frequency stability and long term accuracy, both GPS-locked and Holdover mode .. Economic, reliable and highly compact board level integration .. 1 to 4 1PPS and 10MHz outputs of each type, avoiding the host equipment a useless and noisy distribution / amplification stage .. Phase alignment of all outputs within ±10ns with “0 crossing” 1PPS / 10MHz .. Quick and easy integration thanks to a wide range of connectivity, such as board to board, ribbon cable or coax connectors .. Available in several Oscillator choices, providing different degree of accuracy, low phase noise, stability & holdover capability .. Optional PPS input instead of GPS Typical Applications .. Base stations: WIMAX, WIBRO, 3G and 4G .. Broadcasting: DAB, DVB-T/DVB-H and DTV Introduction Functions
