IC OCXO | MERCURY ™ DIL SERIES
RFPO65
The RFPO65 is from the world’s first ASIC‐based OCXO product family and utilizes Rakon’s patented Mercury™ ASIC technology. This Stratum
3 compliant oscillator delivers temperature stability as low as ±10ppb (over ‐20 to 70°C) and is capable of short term aging of typically less
than ±2ppb per day.
With a highly integrated oven included, the RFPO65 ensures short warm‐up times and consumes very low power – only 350mW at room
temperature. The ASIC architecture delivers a 1000x reliability improvement when compared to traditional discrete OCXOs. The RFPO65 is
available in an industry standard, Dual‐In‐Line (DIL) package.
