The **M3V14T1J-R** is a high-performance **VCXO (Voltage Controlled Crystal Oscillator)** manufactured by Jauch Quartz. It is designed for applications requiring high stability and frequency modulation capabilities in a compact surface-mount package. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Frequency Range** | Typically available from 1.0 MHz to 52.0 MHz | | **Supply Voltage (Vcc)** | 3.3 V (Standard) | | **Package Size** | 7.0 x 5.0 mm (SMD) | | **Output Type** | HCMOS / LSTTL Compatible | | **Control Voltage (Vc)** | 1.65 V ± 1.5 V | | **Frequency Pulling Range** | ± 50 ppm to ± 100 ppm (standard) | --- ### 2. Functional Description As a **VCXO**, this component allows the output frequency to be adjusted (steered) by applying an external DC control voltage. * **Frequency Pulling:** The "Pulling Range" indicates how much the frequency can deviate from the nominal value. This is critical for Phase-Locked Loops (PLL) to synchronize with external signals. * **Stability:** It offers high temperature stability, ensuring the base frequency remains consistent despite environmental changes. * **Tri-state Function:** Pin 2 usually serves as a "Stop" or "Enable" function, allowing the output to go into a high-impedance state for power saving or bus sharing. --- ### 3. Pin Configuration | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | **Vcon** | Control Voltage (Input to adjust frequency) | | **2** | **E/D or NC** | Enable/Disable (Tri-state) or No Connection | | **3** | **GND** | Ground | | **4** | **Output** | HCMOS Output Signal | | **5** | **NC** | No Connection | | **6** | **Vcc** | Supply Voltage (+3.3V) | --- ### 4. Common Applications Due to its ability to fine-tune frequency via voltage, the M3V14T1J-R is commonly found in: * **Telecommunications:** Base stations and switching equipment. * **Networking:** Ethernet synchronization and clock recovery. * **Audio/Video:** Professional broadcasting equipment requiring precise clock alignment. * **Embedded Systems:** Microcontrollers requiring external high-stability clock sources. ---
