Low Power Programmable 32.768 Oscilllator

The SiT1533 is an ultra-small and ultra-low power 32.768 kHzoscillator optimized for mobile and other battery-powered applications. The SiT1533 is pin-compatible and footprint compatible to existing 2012 XTALs when using the SiTime solder-pad layout (SPL). And unlike standard oscillators, the SiT1533 features NanoDrive™, a factory programmable output that reduces the voltage swing to minimize power. The 1.2V to 3.63V operating supply voltage range makes it an ideal solution for mobile applications that incorporate a low-voltage, battery-back-up source such as a coin-cell or super-cap.

• Small SMD package: 2.0 x 1.2mm (2012)
• Ultra-low power: 900nA (typ)
• NanoDrive™ reduced swing oscillator output
• Operates down to 1.2V
• <100 ppm frequency stability over-40°C to +85°C temp range
