The stability over temperature is also a priority metric given the automotive, aerospace, transportation, and alternative variable temperature environments that this oscillator family is expected to encounter.
The maximum frequency deviation over temperature is specified to be at most ±25ppm, and the stability typically stays within a ±10ppm over an industrial temperature range (-40°C to +85°C), as shown in Fig. 5.
The ASADV, ASDDV, and ASEDV Continuous Voltage oscillator series are designed to confront the challenges of battery-powered applications. A battery is essentially a variable energy source with a depleting voltage as a function of load and usage. The CMOS integrated circuits within Abracon’s Continuous Voltage oscillator family remove the bias dependency by integrating a wide-range voltage regulator. The current consumption is also kept to a minimum with tight system power budgets in mind.
