SIT1533AI-H4-DCC-32.768E
Overview
The SIT1533AI-H4-DCC-32.768E is an ultra-small MEMS-based 32.768 kHz oscillator designed for low-power timing applications. It serves as a robust alternative to traditional quartz crystals, offering a stable clock source for Real-Time Clocks (RTCs) and power-management functions in compact electronics. With a wide supply voltage range from 1.5V to 3.63V, it integrates easily into various battery-powered system architectures.
Why Choose This Part
This MEMS oscillator eliminates the need for external load capacitors and is far more resistant to mechanical shock and vibration compared to quartz tuning-fork crystals. Its ultra-small 2012 SMD package saves significant PCB area, while the NanoDrive programmable output swing can be used to further reduce system power consumption.
Applications
Key Specifications
Getting Started
To implement this part, connect VDD to a stable supply between 1.5V and 3.63V and place a 0.1 microfarad decoupling capacitor near the VDD pin. Since it is an active oscillator rather than a passive crystal, the output should be connected directly to the EXTCLK or OSC_IN pin of the MCU, bypassing the internal XTAL oscillation circuit. No external load capacitors are required on the output line.
