The **M3V62V1CJ-R** is a high-performance **Voltage Controlled Crystal Oscillator (VCXO)** manufactured by **NDK (Nihon Dempa Kogyo)**. It is primarily used in telecommunications and high-speed data networking for precise timing and clock generation. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Output Type** | CMOS | | **Supply Voltage ($V_{CC}$)** | +3.3V (Typical) | | **Frequency Range** | 1.5 MHz to 54 MHz | | **Package Size** | 7.0 x 5.0 mm (6-pad SMD) | | **Operating Temperature** | -40°C to +85°C | | **Frequency Pulling Range** | Min ±90 ppm to ±100 ppm | --- ### 2. Functional Characteristics #### A. Voltage Control Function Unlike standard fixed-frequency oscillators, the "V" in VCXO indicates that the output frequency can be slightly adjusted (tuned) by varying the input voltage on the **Control Voltage Pin**. This is essential for: * Phase-Locked Loops (PLLs). * Synchronizing clock signals between different pieces of hardware. * Compensating for frequency aging. #### B. Low Jitter & High Stability The M3V series is designed for low phase noise. In high-speed communication, "jitter" (timing uncertainty) can cause data errors. This part ensures a stable clock edge even in electrically noisy environments. #### C. CMOS Output It provides a Square Wave (CMOS level) output, making it directly compatible with most modern FPGAs, Microcontrollers, and DSPs without needing complex interface circuitry. --- ### 3.
