MD-203 I C Interface Oven Controlled Crystal Oscillator Preleminary version 2 MD-203 The MD-203 is a Vectron module that contains a medium size ovenized crystal oscillator and an I2C interface that communicates with an onboard EEPROM and temperature sensors. The interface enables the customer to improve upon the already exceptional stability of the oscillator. Provided in a fully hermetic 25 x 25 mm package mounted on a SMD spreader board. The device is capable of aging rates of 0,5 ppb/day and temperature stabilities of 8ppb from -40 to 85 °C. Use of the information provided in the I2C interface provides a cost effective means of improving stability by as much as a factor of 10 depending upon environmental conditions.
