Low power MEMS clocks pursue industrial IoT
These reference clocks, with 1Hz to 2MHz nominal values are designed to drive microcontrollers (MCUs) and analog front end (AFE) modules in a range of portable and IoT applications such as railroad activity sensors in harsh environments, seismic sensor interface applications, and personal medical diagnostics.
The current draw of 2-microamps enables 10 year battery life from a coin cell and both products are packahed in a 1.2 square millimeter chip-scale package. Accuracy is +/-50ppm in the case of the SiT1569 and +/-5ppm in the case of the SiT1576.
Samples of the SiT1576 Super-TCXO and SiT1569 oscillator are available with production volume iplanned for 3Q17.
