The **M3V13T2AJ-R** is a high-performance **Voltage Controlled Crystal Oscillator (VCCO)** or VCXO, typically manufactured by companies like Jauch Quartz or similar frequency control specialists. It is designed for applications requiring high stability and frequency tuning capabilities. --- ### 1. Technical Specifications The following table summarizes the key electrical characteristics of the M3V13T2AJ-R: | Feature | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Package Type** | SMD (Surface Mount Device) | | **Package Size** | 3.2 x 2.5 mm (Standard 4-pad/6-pad) | | **Supply Voltage (Vcc)** | 3.3V DC (Typical) | | **Output Type** | HCMOS / LVCMOS | | **Frequency Stability** | ±25 ppm to ±50 ppm (Depending on variant) | | **Pulling Range** | ±100 ppm (Minimum) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ### 2. Functional Pins and Description A VCXO differs from a standard oscillator because it includes a "Control Voltage" pin that allows the output frequency to be adjusted slightly. 1. **V_control (Pin 1):** Applying a voltage here (usually 0V to 3.3V) shifts the output frequency. 2. **GND (Pin 2):** Ground connection. 3. **Output (Pin 3):** The high-frequency clock signal (square wave). 4. **Vcc (Pin 4):** Power supply input. --- ### 3. Key Features * **Small Form Factor:** The 3225 package size makes it ideal for compact PCB designs. * **Low Phase Jitter:** Optimized for data communication and high-speed signal processing. * **Wide Pullability:** The ability to "pull" or tune the frequency by ±100 ppm allows for precise synchronization with other clock sources. * **RoHS Compliant:** The "-R" suffix typically denotes compliance with environmental standards (Lead-free). --- ### 4. Typical Applications * **Phase-Locked Loops (PLL):** Used as the adjustable clock source to lock onto an external reference. * **Networking:** Base stations, routers, and switches for data synchronization. * **Broadcasting:** Video/Audio processing equipment where precise timing is required. * **Fiber Optics:** SONET/SDH and Ethernet transmission systems.
