RFPO50 Datasheet, PDF (1/2 Pages) TEMEX – The RFPO50 is from the world’s first ASIC‐based OCXO product

IC OCXO | MERCURY ™ MINIATURE SERIES
RFPO50
The RFPO50 is from the world’s first ASIC‐based OCXO product family and utilizes Rakon’s patented Mercury™ ASIC technology. It 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 RFPO50 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.
