Overview

The SIT1602BI-23-33E-12.000000 is a 12 MHz MEMS-based fixed-frequency oscillator from SiTime's SiT1602 series. This high-performance timing solution operates at 3.3V and provides a stable HCMOS/LVCMOS output across the industrial temperature range of -40 to +85 degrees Celsius. It features an active-high Enable/Disable function on pin 1 to assist with power management in sensitive designs.

Why Choose This Part

Utilizing MEMS technology, this oscillator offers superior reliability (500 million hours MTBF) and resistance to shock and vibration compared to traditional quartz crystals. The low supply current of 4.5mA max and the integrated Enable/Disable function make it suitable for power-constrained applications.

Applications

Microcontroller Clocking
Provides a precise 12 MHz external clock source for MCUs that require better stability than internal RC oscillators.
Industrial Automation
Reliable timing for PLC communication modules and industrial sensors operating in harsh thermal environments.
Communication Interfaces
Acts as a reference clock for low-speed serial protocols and USB-to-UART bridges requiring 12 MHz timing.

Getting Started

Ensure a 0.1uF bypass capacitor is placed as close as possible to the VDD pin for noise suppression. Since this is a complete oscillator module, no external load capacitors or quartz tuning are required; simply connect the output directly to the target IC clock input.
