MSC now offers the DSO321SR-32K crystal oscillator from Daishinku Corporation (KDS). This 32.768 kHz crystal oscillator features a frequency drift of only ±35 ppm over a wide temperature range from -40°C to +85°C.

Typically, in this frequency range of 32.768 kHz tuning-fork crystals, whose parabolic frequency drift versus temperature curve over the same temperature range from -40°C to +85°C causes a variation of about -150 ppm, are used. Due to the special AT-cut of the DSO321SR-32K, a 32.768 kHz crystal oscillator with a significantly higher frequency stability is now available for the first time.

Additional features of the DSO321SR-32K include a compact 3225 size package (3.2 mm x 2.5 mm), a relatively low current consumption of 35 µA typical and a wide operating voltage range from 1.62 V to 5.5 V.

The DSO321SR-32K, which is lead-free and RoHS compliant, is ideally suited for use in timer module and real-time clock (RTC) applications.
