SiTime SiT1566 / SiT1568 Super TCXO Oscillators
SiTime SiT1566 and SiT1568 Super TCXO Oscillators provide 32.768kHz ±5ppm all-inclusive frequency stability. SiTime SiT1566 and SiT1568 low power (4.5µA) temperature-compensated crystal oscillators feature a 1.2mm2 footprint in a 1.5mm x 0.8mm CSP package and require no external bypass cap. SiT1568 includes in-system auto-calibration. SiT1566 and SiT1568 provide high stability for reduced system power and fewer network timekeeping updates. SiTime SiT1566 and SiT1568 are ideal for use in smart watches, health and wellness monitors, smart utility meters, and more.
