The **M3STV-5WA-R** is a specific electronic component, typically classified as a **Crystal Oscillator** or a high-precision **Voltage Controlled Crystal Oscillator (VCXO)**, often manufactured by companies like **Taitien** or similar frequency control specialized brands. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. Key Technical Specifications The part number follows a standard industry nomenclature for frequency control devices. | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | VCXO / Crystal Oscillator | Voltage Controlled Crystal Oscillator | | **Package Size** | 7.0 x 5.0 mm | Standard 6-pad SMD (Surface Mount Device) | | **Supply Voltage** | 5.0V (Standard) | Indicated by the "5" in the suffix | | **Output Type** | CMOS / TTL | Square wave output for digital circuits | | **Frequency Stability** | ±25ppm to ±50ppm | Variation over temperature range | | **Pullability** | ±50ppm to ±100ppm | Range the frequency can be adjusted via voltage | --- ### 2. Pin Configuration (Typical 6-Pad SMD) For a 7x5mm VCXO like the M3STV-5WA-R, the pinout usually follows this standard: 1. **Pin 1: Voltage Control (V_c)** - Input voltage used to "pull" or adjust the output frequency. 2. **Pin 2: Tri-state / No Connect** - Enables or disables the output (High Impedance). 3. **Pin 3: Ground (GND)** - Connection to the system common ground. 4. **Pin 4: Output** - The clock signal output. 5. **Pin 5: No Connect / NC** - Internal use or placeholder. 6. **Pin 6: Supply Voltage (Vdd)** - Power input (+5V). --- ### 3. Part Number Breakdown While manufacturer codes vary slightly, the "M3STV" series generally decodes as follows: * **M3S**: Series identifier (Surface Mount, 7x5mm). * **T**: Tri-state function capability. * **V**: Voltage Control (VCXO) functionality. * **5**: 5.0V Operating Voltage. * **W**: Operating Temperature Range (typically -40°C to +85°C). * **A**: Specific Frequency Stability or Pulling Range code. * **R**: Tape & Reel packaging. --- ### 4. Typical Applications This component is used in circuits where a precise clock signal is required but needs to be slightly adjustable or synchronized with another signal: * **Phase-Locked Loops (PLL):** For frequency synthesis. * **Telecommunications:** Base stations and networking hardware. * **Digital Video:** Synchronizing audio/video bitstreams. * **Clock Recovery:** Regenerating clock signals from data streams. --- ### 5.
