SiT1533 Datasheet

The SiT1533 is an ultra-small and ultra-low power 32.768 kHz oscillator optimized for mobile, wearable, and other battery-powered applications where space and power are critical. The MEMS-based SiT1533 is pin-compatible and footprint-compatible to existing 2012 quartz crystals (XTALs) when using the SiTime solder-pad layout (SPL), making them an ideal XTAL replacement. And unlike standard oscillators, the SiT1533 features NanoDrive™, a factory-programmable output that reduces the voltage swing compared to LVCMOS output, to minimize power. The 1.2 V to 3.63 V operating supply voltage range makes it an ideal solution for mobile applications that incorporate a low-voltage, battery-backup source, such as a coin cell or supercap.
