TFC Introduces the Smallest RTC Solution – 32.768 kHz OX/OY Series - March 2014

Nowadays there is an increasing need for miniaturized and low power consumption real-time clock (RTC) solution to meet the demands of mobility and extended battery life in smart phones, tablet PCs, digital systems and other mobile electronics. 32.768kHz crystal oscillators, as a typical real-time clock solution, are widely used in the industry due to their high frequency accuracy and stability. 

TFC has years of experience in manufacturing high stability crystal oscillators for various demanding applications. Besides a comprehensive line of 32.768kHz crystal resonators addressing the diverse form factor requirements, Taitien has introduced a new line of 32.768kHz crystal oscillators, 32.768kHz OX/OY series, specifically developed for significantly higher frequency stability and compact package required for real-time clock applications in products such as handheld consumer devices. 

TFC's 32.768kHz OX/OY series utilize smallest-in-class AT-Cut crystal oscillator in an industry standard SMD package of 2.5x2.0mm. Generally, AT-Cut crystal oscillators provide excellent frequency-temperature stability, capable of achieving <2 seconds error for 24hr of continuous operation compared to >8 seconds over the same period for oscillators using tuning fork crystals. Combined with low-power ASIC design, TFC's 32.768kHz OX/OY series deliver the benefits of small form factor, low current consumption of <60uA and tight frequency stability of ±25ppm over the industrial temperature range of -40°C to +85°C, as well as fast start-up time at 2 ms. 

Taking advantages of TFC's design and fabrication expertise on 32.768kHz crystal resonators and quartz oscillators, TFC's 32.768kHz OX/OY series would be an optimal solution for real-time clock applications in system designs required exceptional timekeeping accuracy and reliability.
