The **W2XM-1Z1V2-R** is a specific electronic component typically categorized as a **Surface Mount (SMT) Crystal Oscillator**. These components are fundamental in electronics for providing a stable clock signal or frequency reference for microprocessors, wireless modules, and communication systems. --- ### 1. General Specifications The part number follows a specific nomenclature used by manufacturers (often associated with brands like **TXC** or similar frequency control suppliers). Below are the typical electronic characteristics of this series: | Feature | Description | | :--- | :--- | | **Component Type** | Quartz Crystal Oscillator (SPXO) | | **Package Size** | Usually 2.0 x 1.6 mm or 2.5 x 2.0 mm (Ultra-miniature) | | **Mounting Type** | Surface Mount Device (SMD) | | **Output Type** | CMOS / LVCMOS | | **Supply Voltage** | Typically 1.8V to 3.3V | | **Frequency Stability** | ±10ppm to ±50ppm (depending on grade) | ### 2. Electronic Structure and Pinout This part is a 4-pin active oscillator. Unlike a passive crystal (which needs external capacitors and an IC-based inverter), this part contains the quartz blank and an integrated circuit (IC) to drive the oscillation. | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | OE or NC | Output Enable (High = Active) or No Connection | | **2** | GND | Ground / Common | | **3** | Output | Frequency Clock Output | | **4** | VDD | Supply Voltage Power | ### 3. Key Electronic Functions * **Piezoelectric Effect:** Uses a mechanical quartz resonator that vibrates at a specific frequency when voltage is applied. * **Signal Buffering:** The internal IC squares the sine wave into a digital CMOS square wave, making it compatible with modern MCUs. * **Low Phase Jitter:** Designed for high-speed data transmission where timing precision is critical. ### 4. Typical Applications 1. **Mobile Electronics:** Smartphones and tablets where PCB space is limited. 2. **IoT Modules:** Bluetooth, Wi-Fi, and Zigbee modules requiring precise timing for synchronization. 3. **Wearables:** Smartwatches and fitness trackers due to the low power consumption and small footprint. --- ### 5. Part Number Decoding (Typical) While internal codes vary by vendor, the "R" suffix often denotes **Tape & Reel** packaging for automated pick-and-place assembly machines.
