IC OCXO | MERCURY ™ MINIATURE SERIES www.rakon.com sales@rakon.com Page 1 of 2 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.. Standard Specifications Parameter Min. Typ. Max. Unit Test Condition / Description Nominal frequency 5 – 50 MHz Standard frequencies: 10, 12.8, 19.2, 19.44, 20, 24.576, 25, 26, 30.72 and 40MHz Frequency calibration ±0.5 ppm Initial accuracy at 25°C ±2°C Reflow shift ±1 ppm Pre to post reflow ∆F (measured ≥ 60 minutes after reflow) Frequency stability over temperature in still air ±10 – ±100 ppb Reference to (FMAX + FMIN)/2 Frequency slope ΔF/ΔT in still air ±0.5 – ±2 ppb/°C Temperature ramp ≤ 1°C/minute Operating temperature range -40 85 °C Supply voltage stability ±10 ppb ±5% variation, frequency ≤ 26MHz Load sensitivity ±10 ppb ±5pF / ±10% variation, frequency ≤ 26MHz Warm-up time < 3 minutes The time needed for the frequency to be within ±20ppb of the frequency after 1 hour, at 25°C. This parameter is frequency, assembly and operating history dependent Acceleration sensitivity < 2 ppb/g Gamma vector of all 3 axes, 30 to 1500Hz Long term stability (ageing) < ±2 ppb ppm ppm Per day (after 30 days of continuous operation) First year 10 years Root Allan Variance (20MHz) 7.10-11 tau = 1.0s Supply voltage (Vcc) 2.7 – 5.5 V ±5% Input power (warm up) 1000 800 mW mW -40 to 85°C devices -20 to 70°C devices Input power (steady state in still air at 25°C) 400 350 mW mW -40 to 85°C devices -20 to 70°C devices Control voltage (Vc) 0.5 – 2.5 V The GND of Vc needs to be connected directly to pin 2 as ground lead impedance may cause performance degradation Frequency tuning ±5 ppm Reference to frequency at Vc=1.5V Slope +8 ppm/V Linearity 1 1 % Port input impedance 80 kΩ Modulation bandwidth 3.5 kHz Oscillator output – C/Sinewave 0.8 1.1 Vpk-pk At minimum supply voltage, 10kΩ//10pF load 1 The difference between the measured tuning characteristic and an ideal straight line fitted through it, expressed as a percentage of the total tuning range.
