IC OCXO | MERCURY ™ MINIATURE SERIES www.rakon.com sales@rakon.com Page 1 of 2 RFPO55 The RFPO55 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 RFPO55 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. Standard Specifications Parameter Min. Typ. Max.
