Based on the part number **MV22T2CD-R**, this component is a high-precision **Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO)**, typically manufactured by companies like Microchip (formerly Vectron) or similar timing component specialists. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. Technical Specifications The "MV" series generally refers to miniature, high-stability oscillators designed for telecommunications and precision timing. | Feature | Specification | | :--- | :--- | | **Component Type** | VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) | | **Package Size** | Typically 5.0 x 3.2 mm or 7.0 x 5.0 mm SMD | | **Output Type** | CMOS or Clipped Sine Wave (Model dependent) | | **Supply Voltage** | Usually 3.3V (standard for the 'T' or 'C' designations) | | **Frequency Stability** | ±0.5 ppm to ±2.5 ppm (over temperature range) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ### 2. Part Number Breakdown (Typical Syntax) While internal naming conventions vary by manufacturer, the code usually follows this logic: * **MV:** Series prefix (Miniature VCTCXO). * **22:** Often denotes the package size or a specific frequency stability tier. * **T:** Temperature range indicator (Commonly -40 to +85°C). * **2:** Voltage code (Often representing 2.5V or 3.3V). * **CD:** Output and Tuning characteristic (CMOS output with Control Voltage). * **-R:** RoHS compliant / Tape & Reel packaging. --- ### 3. Key Electronic Functions * **Temperature Compensation:** Uses an internal compensation network to counteract frequency drift caused by ambient temperature changes. * **Voltage Control (VC):** Features a "Control Voltage" pin (Pin 1) that allows the user to manually tune or "pull" the output frequency to a specific value. * **Phase Noise:** Designed for low phase noise, making it suitable for GPS, LTE base stations, and high-speed networking hardware. --- ### 4. Typical Applications These parts are found in circuits where timing precision is critical but the space/power for a full Oven Controlled Oscillator (OCXO) is unavailable: 1. **Wireless Infrastructure:** Small cells, repeaters, and base stations. 2. **GPS/GNSS Receivers:** High-accuracy positioning. 3. **Broadband Access:** SONET/SDH and Ethernet synchronization. 4. **Test & Measurement:** Handheld frequency counters and signal generators. ---
