The **M5R25ZH-R** is a specific electronic component, primarily identified as a high-performance **Crystal Oscillator**. These components are essential for providing a stable clock signal to microprocessors and digital circuits. --- ### 1. General Specifications The "M5R" series is typically manufactured by vendors like *MtronPTI*. Below are the technical characteristics associated with this part number: | Feature | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package / Case** | 5.0 x 7.0 mm (SMD) | | **Output Type** | CMOS / TTL | | **Frequency Stability** | ±25 ppm (Standard for the '25' code) | | **Voltage Supply** | 5.0V (Standard for the '5' code) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the '-R' suffix) | --- ### 2. Key Electronic Characteristics #### A. Frequency Stability The "25" in the part number signifies a frequency stability of **±25 parts per million (ppm)**. This indicates the maximum deviation the frequency will have from its nominal value due to temperature changes or aging. #### B. Supply Voltage (Vdd) The "5" in the prefix usually indicates a **5.0V DC** operating voltage. This makes it compatible with older legacy systems and specific high-power industrial logic gates. #### C. Tri-State Functionality Most oscillators in this series feature a "Tri-state" or "Enable/Disable" function on Pin 1. * **High/Floating:** The oscillator outputs the clock signal. * **Low:** The output goes into a high-impedance state, reducing power consumption. --- ### 3. Pin Configuration (Typical 4-Pad SMD) For the 5x7mm surface mount package, the pinout is generally standardized: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable or No Connection | | **2** | GND | Ground / Case Connection | | **3** | Output | The generated clock signal | | **4** | Vdd | Power Supply (+) | --- ### 4. Common Applications * **Networking:** Used in routers and switches for timing synchronization. * **Industrial PC:** Provides the master clock for embedded processors. * **Data Communications:** Ensures accurate data transfer rates in serial communication. ---
