1 MD-403 I2C InterfaceOven Controlled Crystal Oscillator MD-403 The MD-403 is a Vectron module that contains a medium size ovenized crystal oscillator and an I 2 C 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 13 x 20 x 10.7mm package, the device is capable of aging rates of 1/ day and temperature stabilities of 10 from -40 to 95 C. Use of the information provided in the I 2 C interface provides a cost effective means of improving stability by as much as a factor of 10 depending upon environmental conditions.
