Mobile information terminals such as smart phones equipped with short-distance wireless communication function such as Bluetooth or W-LAN in addition to the verbal communication function is becoming increasingly popular nowadays. Previously, a dedicated reference clock signal source was needed in order to equip the short-distance wireless communication function in addition to the verbal communication function. For this reason, the need for a TCXO that can provide reference clock signal to both of the two functions mentioned above has increased amidst the ambivalent two needs: miniaturization and multifunction. In order to meet these market needs, we have developed the world’s smallest TCXO with two outputs of the same frequency.
This TCXO can provide reference clock signal to both of the two functions via independent outputs. Also, its Enable/Disable function offers more efficient power management, leading to lower power consumption.
Previously, multiple reference clock sources were needed for the short-distance wireless communication function of mobile phones. But this TCXO alone can provide the reference clock signal to both of the two functions. This will help downsize the circuit boards in mobile information terminals. Moreover, the Enable/Disable function offers lower power consumption, longer battery life and reduced environmental load.
