SiT1618AA-81-25N-29.491200概述

    Product Introduction
    The SiT1618 is a high-performance, standard frequency, and high-temperature oscillator developed by SiTime Corporation. It is designed for demanding industrial, medical, automotive, avionics, and other high-temperature applications such as industrial sensors, PLCs, motor servos, outdoor networking equipment, medical video cameras, and asset tracking systems. The SiT1618 offers excellent total frequency stability as low as ±20 ppm and supports a supply voltage range of 1.8V to 3.3V, making it suitable for both low-power and high-stability requirements.
    Technical Parameters
    The SiT1618 features 33 standard frequencies ranging from 7.3728 MHz to 48 MHz, making it highly versatile for various applications. The oscillator operates across a wide temperature range (-40°C to 125°C), with an option for -55°C under specific models like SiT8920 and SiT8921. Key technical specifications include:
    - Supply Voltage: 1.8V to 3.3V
    - Current Consumption: 3.4 mA typical at 1.8V, reducing to μA levels in standby mode
    - Frequency Stability: ±20 ppm inclusive of initial tolerance, first-year aging, and temperature variations
    - Output Compatibility: LVCMOS/LVTTL compatible
    - Package Sizes: Industry-standard options include 2.0 x 1.6 mm, 2.5 x 2.0 mm, 3.2 x 2.5 mm, 5.0 x 3.2 mm, and 7.0 x 5.0 mm
    Product Features and Advantages
    The SiT1618 stands out due to its high frequency stability, low power consumption, and wide operating temperature range. Its programmable drive strength feature allows optimization of rise and fall times for specific applications, enhancing system performance and EMI reduction. Additionally, the SiT1618 is compliant with RoHS and REACH standards, ensuring environmental friendliness and compatibility with modern manufacturing practices.
    Application Cases and Usage Recommendations
    The SiT1618 is ideal for environments requiring precise timing solutions, such as industrial automation, telecommunications, and automotive systems. For example, in industrial sensors, the SiT1618 ensures accurate timing even under extreme temperatures, improving reliability and accuracy. Users should ensure proper power supply decoupling with a 0.1 µF capacitor between Vdd and GND to maintain optimal performance. When configuring the OE/ST/NC pin, a pull-up resistor of 10 kΩ or less is recommended if pin 1 is not externally driven.
    Compatibility and Support
    The SiT1618 is fully compatible with industry-standard packages, facilitating seamless integration into existing designs. SiTime provides comprehensive support, including field programming capabilities through the Time Machine II oscillator programmer, enabling real-time customization and rapid prototyping.
    Common Issues and Solutions
    Users may encounter issues related to incorrect pin configuration or power supply noise. To address these:
    - Ensure proper pin configuration based on the intended mode (OE, ST, or NC).
    - Implement adequate filtering on the power supply lines to mitigate noise effects.
    Conclusion and Recommendation
    Overall, the SiT1618 offers a robust solution for applications demanding high frequency stability and wide temperature operation. Its programmable features, low power consumption, and compatibility make it a top choice in the market. Highly recommended for applications requiring reliable timing solutions in harsh environments.
    This article synthesizes the technical manual content into a concise yet comprehensive overview, highlighting the SiT1618's unique capabilities and practical application insights.
