MD-173
MD-173 Coefficient Oven Controlled Crystal Oscillator (OCXO)
Overview
The MD-173 is a “Coefficient Oscillator” (CCXO) that contains a high-stability ovenized crystal oscillator and an I2C 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 70ºC. Use of the information provided in the I2C interface provides a cost effective means of further improving temperature stability.Downloads
