    Functional Description:

    The H325 10MHz OCXO represents an industry-standard frequency reference source with a volume production record of high reliability for a wide range of RF applications. Due to this large-scale production, the H325 presents a cost-effective solution to many customer requirements while providing industry-leading performance.

    With temperature stability as good as ±3 ppb over the range of -40°C to +85°C, the H325 outperforms many competitor parts in the same package size. The H325 comes in a 25.8 mm x 25.8 mm x 12.8 mm package, lending itself to applications with tight footprint requirements.

    An optional reference voltage output gives the user a stable, ovenized voltage reference to derive their control voltage (EFC) from. This will result in less skew over temperature than using contemporary methods of EFC generation.
