C interface Oven Controlled Crystal Oscillator
MD-173
MD-173
The MD-173 is a Vectron “Coefficient Oscillator” (CCXO) that contains a high-stability ovenized crystal oscillator and an I
2
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 I
2
C interface provides a cost effective means of further improving temperature stability.
Features
• Reflow process compatible
• Uncorrected temperature stability to 0.4 ppb
• Aging rate to 0.06 ppb/day
• Frequency range 5 to 20 MHz
• Standard frequencies: 5, 10, 12.8, 20 MHz
• I
2
C interface with frequency coefficients, temperature
sensor, and current sensor
Applications
• LTE base stations
• Rubidium replacement
• Military communication equipment
