Key Technical Specifications Below is a breakdown of the primary electronic characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Package Type** | J-Lead Ceramic Surface Mount | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage (Vcc)** | 3.3V DC (Standard) | | **Frequency Range** | Typically 1.000 MHz to 160.000 MHz (Model dependent) | | **Frequency Stability** | ±25ppm to ±100ppm (Depending on specific sub-variant) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Control Voltage** | 0.3V to 3.0V (Typical range for 3.3V supply) | --- ### 2. Functional Electronic Parts The internal architecture of the M3V23T2AJ-R consists of several integrated sub-systems: 1. **Quartz Crystal Resonator:** The heart of the device, providing a stable reference frequency through the piezoelectric effect. 2. **Varactor Diode:** This is the "control" element. By changing the voltage on this diode, its capacitance changes, which "pulls" the crystal frequency slightly higher or lower. 3. **Oscillator IC:** An active circuit that maintains the oscillation of the crystal and converts it into a usable square wave (CMOS). 4. **Output Buffer:** Ensures the signal is strong enough to drive downstream components (like FPGAs or CPUs) without degrading the waveform. --- ### 3. Pin Configuration (Typical J-Lead) The device typically utilizes a 4-pin or 6-pin J-lead configuration to save PCB space while providing mechanical stability. * **Pin 1 (V_control):** Receives the analog voltage to adjust the frequency. * **Pin 2 (Enable/Disable):** Allows the output to be turned on or off to save power. * **Pin 3 (GND):** Common ground. * **Pin 4 (Output):** The generated clock signal. * **Pin 6 (Vcc):** Positive power supply input. --- ### 4. Common Applications * **Phase-Locked Loops (PLLs):** Used to synchronize two different clock signals. * **Telecommunications:** SONET/SDH, ATM, and Ethernet synchronization. * **Digital Video:** Jitter reduction in high-definition video broadcasting equipment. * **Instrumentation:** Signal generators and frequency synthesizers. ---
