The **M3V14V2CJ-R** is a specific part number for a **Voltage Controlled Crystal Oscillator (VCXO)**, typically manufactured by companies like Jonson or similar frequency control component specialists. It is designed for high-precision timing applications where the output frequency needs to be adjusted or "tuned" by an external voltage. --- ### 1. Key Technical Specifications The part number encodes specific parameters regarding its physical and electrical behavior. Below is a breakdown of the typical specifications for this series: | Feature | Specification Details | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Package Size** | 3.2mm x 5.0mm (Standard SMD) | | **Supply Voltage** | 3.3V DC (Common for 'V' series) | | **Output Type** | CMOS / HCMOS | | **Frequency Stability** | Typically ±25ppm to ±50ppm | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Pullability** | ±100ppm (Minimum) | --- ### 2. Functional Description As a **VCXO**, this component differs from a standard fixed oscillator in the following ways: * **Frequency Control (Pin 1):** Unlike a standard oscillator where Pin 1 might be "No Connect" or "Enable/Disable," Pin 1 on the M3V14V2CJ-R is the **Voltage Control (Vc)** pin. * **Tuning:** By applying a voltage (usually 0V to 3.3V) to Pin 1, the user can "pull" the output frequency slightly higher or lower. This is critical for Phase-Locked Loops (PLLs) and synchronizing data streams. * **Phase Noise:** These parts are engineered for low jitter, making them suitable for high-speed communication interfaces. --- ### 3. Pin Configuration (Typical) Most 3.2x5mm VCXOs follow a standard 4-pin or 6-pin layout: | Pin # | Function | Description | | :--- | :--- | :--- | | **1** | **V_c** | Control Voltage (Adjusts the frequency) | | **2** | **E/D** | Tri-state / Enable-Disable (Optional) | | **3** | **GND** | Ground | | **4** | **Output** | Frequency Output Signal (CMOS) | | **5** | **N/C** | No Connection | | **6** | **Vdd** | Power Supply (3.3V) | --- ### 4. Common Applications * **Telecommunications:** Base stations and networking hardware. * **Video/Audio:** Digital video broadcast equipment requiring clock synchronization. * **Clock Recovery:** Used in circuits that need to "lock" onto an incoming data signal frequency. * **Test & Measurement:** Precision instruments requiring fine-tuning of clock signals.
