Active

Overview

The SIT5356AI-FQ-33E0-26.000000 is a high-precision 26 MHz Temperature Compensated MEMS Oscillator (TCXO) designed for demanding timing requirements. It offers exceptional frequency stability of +/-100ppb across an industrial temperature range of -40 to 85 degrees Celsius. Utilizing SiTime's silicon MEMS technology, this device provides superior reliability and resistance to shock and vibration compared to traditional quartz-based oscillators.

Why Choose This Part

The primary advantage is the +/-0.1ppm stability, which ensures minimal frequency drift in varying thermal environments. Its MEMS construction eliminates the risk of activity dips and offers much higher durability than quartz crystals. Additionally, the 3.3V LVCMOS output and 5.0mm x 3.2mm footprint allow for easy integration into standard digital system architectures.

Applications

GNSS and GPS Modules
Provides the high-stability reference clock required for rapid satellite signal acquisition and precise positioning.
Small Cell Base Stations
Acts as a local timing reference for synchronization in wireless infrastructure and telecommunications equipment.
IEEE 1588 PTP Timing
Supports Precise Time Protocol requirements in industrial ethernet switches and networked automation systems.
Precision Instrumentation

Getting Started

To evaluate this part, use a high-bandwidth oscilloscope probe to verify the 26 MHz LVCMOS signal at the output pin. Ensure a 0.1uF bypass capacitor is placed as close as possible to the VDD pin to minimize power supply noise. SiTime also offers the SiT6722 evaluation board for testing Elite Platform oscillators in various system configurations.
