MD-173

In Production

The MD-173 is a Vectron “Coefficient Oscillator” (CCXO) that contains a high-stability ovenized crystal oscillator and an I2 C interface that communicates with temperature and current sensors, and an onboard EEPROM. The interface enables the customer to improve upon the already exceptional stability of the oscillator. Provided in a fully hermetic 28 x 38 mm package, the device is capable of aging rates of ≤ 0.06 ppb/day and uncorrected temperature stabilities of 0.4ppb from 0 to 70 0 C. Use of the information provided in the I2 C interface provides a cost effective means of further improving temperature stability....
