TCXOs Cut Power But Not Stability

Frequency stability is critical in many applications, though often at the cost of a current-consuming reference oscillator. But for designs that need to keep the power low, the T72 Series of temperature-compensated crystal oscillators (TCXOs) from Greenray Industries can operate on a mere 1 mA of current at +3.3 VDC. Available with frequencies from 10 to 50 MHz, these tiny TCXOs are supplied in a 5 x 7 mm ceramic package and are designed for operating temperatures from -40 to +85C while maintaining stability as good as 0.2 ppm. With this almost negligible power consumption, these sources are ideal for portable applications and any circuit that runs on a battery and needs a stable reference frequency. For more, click here.
