High Performance 4TE high (20mm) OEM Synchronization Clock Board Enhanced with Superior Holdover Clock OSA 4501 OEM Clock Oscilloquartz SA / Rue des Brévards 16 / CH-2002 Neuchâtel Switzerland / Tel.+41(0)32 722 55 55 / Fax+41(0)32 722 55 56 [email protected] / www.oscilloquartz.com The OSA 4501 is a very compact 4TE high (20mm) OEM Synchronization Clock Board providing superior time and frequency synchronization at minimal cost and minimal space. Based on the new state-of-the art 19mm high Double Oven Quartz Oscillator OCXO 8863, time and frequency are delivered at the highest level of accuracy and stability for such a minimal size. Numerous configurations are available thanks to the OSA 4501 versatility, to easily adapting any requirements for base stations and broadcast station systems or subsystems as a discrete and inexpensive synchronization solution. The OSA 4501 time and frequency is derived either from a GPS receiver or from a PPS input as an alternative solution. When no valid input is available, the OSA 4501 enters in holdover mode and holds its output frequencies to supply long hours of frequency and phase accuracies. Enhanced with its Aging and Temperature Drift Compensation (ATDC) system, the OSA 4501 is the most stable GPS quartz clock ever in holdover mode, in a so thin form factor, especially in large temperature variations environment and harsh conditions. The OSA 4501 is also fully manageable thanks to its userfriendly Configuration Manager software. Furthermore, the OSA 4501 is highly reliable and totally maintenance-free.
