SiT1618AA-83-18N-12.000000概述

    # SiT1618 Standard Frequency, High Temperature Oscillator
    Product Introduction
    The SiT1618 is a versatile, high-performance standard frequency oscillator designed for industrial, medical, automotive, avionics, and other high-temperature applications. This oscillator features a wide range of selectable standard frequencies between 7.3728 MHz and 48 MHz, making it ideal for a variety of timing-sensitive applications such as industrial sensors, programmable logic controllers (PLCs), motor servos, outdoor networking equipment, medical video cameras, asset tracking systems, and more.
    With an excellent total frequency stability as low as ±20 ppm, the SiT1618 ensures reliable performance across its operational temperature range of -40°C to 125°C. Additionally, the oscillator provides low power consumption at 3.4 mA typical at 1.8V, supporting compatibility with LVCMOS/LVTTL outputs and multiple industry-standard packages. It is RoHS and REACH compliant, making it environmentally friendly without lead, halogens, or antimony.

    - Jitter Performance:
    - RMS Period Jitter: 1.6 to 2.5 ps (f = 20 MHz, Vdd = 2.5V to 3.3V).
    - Peak-to-Peak Period Jitter: 12 to 20 ps (f = 20 MHz, Vdd = 2.5V to 3.3V).
    Product Features and Advantages
    The SiT1618 stands out with its advanced programmable drive strength feature, allowing users to optimize rise/fall times for specific applications. This helps in reducing EMI and improving jitter performance. It also supports capacitive loads up to 60 pF with guaranteed full swing output voltage across temperature.
    Its ability to work within a broad temperature range (-40°C to 125°C) makes it particularly suitable for harsh environments. Additionally, the "no runt" pulses and "no glitch" output during startup or resume further enhance its reliability.
    Application Cases and Usage Recommendations
    The SiT1618 finds applications in critical sectors like industrial automation, where its robustness and precision are essential. For instance, in outdoor networking equipment exposed to extreme temperatures, the SiT1618 ensures stable timing signals.
    To maximize performance:
    - Use a pull-up resistor of 10 kΩ or less if Pin 1 is not externally driven.
    - Always connect a 0.1 µF capacitor between Vdd and GND.
    - Ensure accurate alignment of drive strength settings based on output load requirements to achieve optimal rise/fall times.
    Compatibility and Support
    The SiT1618 supports multiple industry-standard packages, ensuring easy integration with existing designs. SiTime offers comprehensive technical support including field programmable devices via the Time Machine II tool, enabling real-time customization of features. Compatibility with various power supplies ensures seamless integration into diverse electronic systems.
