The **M3V14T2CJ-R** is a specific part number belonging to a series of **Voltage Controlled Crystal Oscillators (VCXO)**, typically manufactured by companies like MtronPTI. These components are critical for frequency control and timing in telecommunications and data processing hardware. --- ### 1. Component Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Voltage Controlled Crystal Oscillator (VCXO) | | **Output Type** | HCMOS / TTL Compatible | | **Package Size** | 9x14 mm J-Lead (Surface Mount) | | **Voltage Supply** | 3.3V (indicated by the "3V" prefix) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Frequency Range** | Typically 1.000 MHz to 160.000 MHz | --- ### 2. Key Electronic Features The M3V14T2CJ-R is designed for precision and stability. Its primary electronic functions include: * **Voltage Control (V_c):** It allows the output frequency to be "pulled" or adjusted by applying a small DC voltage to a control pin. This is essential for Phase Locked Loops (PLL). * **Tri-state Function:** The "T" in the suffix usually indicates a Tri-state (Enable/Disable) function, allowing the output to be disconnected electronically to save power or prevent bus contention. * **Low Jitter:** Designed for high-speed data transmission where timing errors must be minimized. * **J-Lead Packaging:** The "CJ" refers to the ceramic package with J-leads, which provides excellent thermal expansion matching to PCB materials and protects the internal quartz crystal. --- ### 3. Common Applications These oscillators are used in circuits requiring precise synchronization: 1. **Telecommunications:** Base stations, SONET/SDH, and clock recovery circuits. 2. **Networking:** High-speed routers and switches where signal integrity is paramount. 3. **Video Systems:** Digital video processing and broadcast equipment. 4. **Frequency Synthesis:** Acting as the reference clock in complex frequency generation systems. --- ### 4. Typical Connection Diagram When integrating this part into a circuit, the pinout generally follows this standard: ```markdown Pin 1: Control Voltage (Vc) - Adjusts frequency Pin 2: Enable/Disable (Tri-state) Pin 3: Ground (GND) Pin 4: Output (HCMOS Signal) Pin 5: No Connection (NC) Pin 6: Supply Voltage (Vdd - 3.3V) ```
