Pletronix’ OeXO (OCXO equivalent Crystal Oscillators) Series of precision frequency signal generators provides the accuracy and precision of traditional OCXO’s but offers smaller package size and lower power, according to the company. The series is available in three formats and is suited to remote satellite links, point-to-point RF communications, test equipment instrumentation and other applications where a precision frequency reference is needed. Each of the three different styles features a stability of ± 50 ppb over 0°C to +70°C and ± 100 ppb over -40°C to +85°C. Warm-up time to reach the specified frequency is <3 second at any temperature. The Model OeD4 is in a 3.2 mm x 5 mm ceramic LCC package; Model OeA4 is in a 5 mm x7 mm ceramic package, and the Model OeM4 is in a through-hole DIP/DIL package. All are RoHS compliant, available in frequencies from 10 MHz to 40 MHz, and available in 3.3 V and 5.0 V with higher voltages optional. The OeD4 Series oscillators for standard frequencies (10.0 MHz, 19.2 MHz, 20.0 MHz and 26.0 MHz) are $15 in production quantities.
