Rakon’s ‘Mercury’ series of low cost OCXOs bridges a major gap in the market between ultra-stable TCXOs and traditional higher end OCXOs, in terms of cost, stability, size, weight, and power consumption. Using state of the art VLSI techniques, this ASIC-based patented design is a disruptive technology enabling a considerable size reduction in OCXOs. Mercury is also significantly lower in cost than traditional OCXOs, which can consume up to 20 times more power.

Combining oven technology with Rakon’s proprietary ultra-stable temperature compensation, Mercury delivers excellent frequency stabilities in two reflowable surface mount packages: RFPO40 (9.0 x 7.0 mm) and RFPO50 (14.0 x 9.0 mm). 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 350 mW at room temperature. Mercury has superb phase noise of -148dBc/Hz at 10 kHz offset (for a 20 MHz oscillator).

Rakon’s Mercury meets the stringent requirements for small cells, base stations, LTE and LTE-Advanced applications. It is also suitable for use in a variety of other applications including broadcasting, microwave links, instrumentation, satellite communications, network timing and synchronization and IP timing.
