The SiT1569 is a µPower, ultra-small oscillator for frequencies from 1 Hz to 462.5 kHz with ±50 ppm maximum frequency stability over temperature, supply voltage, and aging. It operates from 1.62 V to 3.63 V, draws 3.3 µA at 100 kHz, and has a 1.5 mm × 0.8 mm CSP footprint with 0.6 mm maximum height. The device includes an LVCMOS-compatible output, requires no external bypass capacitors, and is RoHS and REACH compliant. It is rated for commercial (-20°C to 70°C) and industrial (-40°C to 85°C) temperature ranges with a 150 ms to 500 ms start-up time depending on frequency. ESD protection meets HBM 2000 V, CDM 750 V, and MM 200 V standards, and it withstands 20,000 g mechanical shock and 70 g vibration. PFAS-free options are available with the 'P' ordering code.
