In addition, no other device on the market can offer a comparable performance ratio of temperature stability to input power. The SCH101 provides extremely low phase noise perfor- mance for applications where quiet operation is paramount. Unlike traditional OCXO products, SCH-series OCXOs are compensated for trim effect to ensure that temperature stability performance is maintained as the frequency is adjusted to correct for drift over time (aging). The SCH-series of OCXOs also enjoys a higher immunity to orientation and airflow effects, as compared to other contemporary OCXO designs. The standard CO8, or “EURO” package makes the SCH-series OCXO ideal for upgrading existing applications to provide improved temperature stability or to expand the application’s operational temperature range.
