Very low power 9.0×7.0mm OCXOs
Mercury is also significantly lower in cost than traditional OCXOs, which can consume up to 20 times more power, claims the manufacturer. The Mercury series delivers excellent frequency stabilities in two reflowable surface mount packages: RFPO40 (9.0×7.0mm) and RFPO50 (14.0×9.0mm). DIL versions are also available. Short term ageing of less than ±5 ppb per day is achievable with a frequency versus temperature performance of down to ±10 ppb. The highly integrated oven design ensures short warm up times with a power consumption of only 350mW at room temperature. Phase noise is -148dBc/Hz at 10 kHz offset (for a 20 MHz oscillator).
