Overview

The SIT8008BI-23-33E-74.250000 is a high-performance, programmable MEMS oscillator from SiTime providing a stable 74.25 MHz output. Operating at 3.3V, it features an enable/disable function and is housed in a standard 3.2mm x 2.5mm 4-SMD package. This MEMS-based resonator offers superior reliability and resistance to shock and vibration compared to traditional quartz crystal oscillators.

Why Choose This Part

This oscillator features MEMS technology which ensures high reliability and a long operating life, even in high-vibration environments. The 25ppm frequency tolerance and wide industrial temperature range of -40C to 85C ensure consistent performance across varying conditions. Its low-profile 3225 package and 3.3V operation make it an easy drop-in replacement for standard quartz oscillators.

Applications

High-Definition Video Equipment
The 74.25 MHz frequency is a standard clock for HD video interfaces, including HDMI and SDI, used in pixel clock generation.
Ethernet Networking
Provides a reliable reference clock for network interface controllers and switches requiring high-frequency stability.
Industrial Computing
Utilized in embedded systems and PLCs operating in harsh environments where MEMS technology provides better durability than quartz.

Getting Started

To integrate this component, ensure a 0.1uF bypass capacitor is placed as close as possible to the VDD pin. The output should be connected via a short trace to the target IC to maintain signal integrity at 74.25 MHz. Evaluation of the SiTime MEMS family can be performed using the SiT6011 evaluation board designed for 4-pin oscillators.
