The **M3V24T1CJ-R** is a specific surface-mount crystal oscillator produced by **Kyocera**. It belongs to the M3V series, which are Voltage Controlled Crystal Oscillators (VCXOs) designed for high-precision timing and frequency control applications. --- ### 1. Key Technical Specifications The following table outlines the core electronic characteristics of the M3V24T1CJ-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Nominal Frequency** | 24.000 MHz | | **Supply Voltage (Vcc)** | 3.3V (±10%) | | **Output Type** | CMOS | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±50 ppm | | **Package Size** | 7.0 x 5.0 mm (SMD) | | **Control Voltage Range** | 1.65V ± 1.35V | --- ### 2. Functional Components and Pins As a VCXO, this part includes internal circuitry to pull or adjust the output frequency based on an external input voltage. * **VC (Voltage Control):** Pin 1. Applying a voltage here allows the user to fine-tune the 24MHz output frequency. * **Enable/Disable (OE):** Often included on Pin 2 to put the device in a low-power standby mode. * **Vcc and GND:** Power supply pins (3.3V). * **Output:** The clock signal (Square wave CMOS) used by the MCU or DSP. --- ### 3. Application Areas The M3V24T1CJ-R is typically used in circuits where the clock signal needs to be synchronized with an external reference: 1. **Phase-Locked Loops (PLLs):** Used to lock the frequency to an incoming data stream. 2. **Broadcasting Equipment:** Ensuring video and audio signals remain in sync. 3. **Network Infrastructure:** Synchronous Ethernet or SONET/SDH timing. 4. **Set-top Boxes:** Managing digital signal timing. --- ### 4. Circuit Implementation Example When integrating this part into a PCB design, it is standard practice to include decoupling capacitors. ```c // Typical Connection Diagram Logic // Pin 1 (VC) <-- Connect to DAC or Control Voltage // Pin 2 (OE) <-- Connect to Logic High to Enable // Pin 3 (GND) <-- Ground Plane // Pin 4 (OUT) <-- Trace to Microcontroller/Processor // Pin 5 (NC) <-- No Connection // Pin 6 (Vcc) <-- 3.3V with 0.1uF Bypass Capacitor ```
