The **MHO+65TDD-R** is a high-precision electronic component primarily used in timing and frequency control applications. Specifically, it is a **Temperature Compensated Crystal Oscillator (TCXO)** or a specialized Oven Controlled variant (OCXO) depending on the specific series iteration, typically used in high-stability communication systems. --- ### 1. General Specifications Based on the part numbering nomenclature common to manufacturers like MtronPTI, here are the technical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (TCXO/OCXO) | | **Frequency Range** | Typically 1 MHz to 160 MHz (Customized) | | **Supply Voltage** | 3.3V or 5.0V DC (Standard) | | **Output Type** | CMOS / TTL Compatible | | **Stability** | ±0.1 ppm to ±2.5 ppm (Temperature dependent) | | **Package Style** | 14-pin DIP or Half-size DIP footprint | --- ### 2. Breakdown of the Part Number The alphanumeric string provides specific details about the component's build: * **MHO:** Often indicates the product series (Metal Hybrid Oscillator). * **6:** Usually refers to the supply voltage (e.g., 5.0V or 3.3V variant). * **5:** Specifies the frequency stability over the operating temperature range. * **TD:** Represents the temperature range (e.g., -40°C to +85°C). * **D:** Denotes the output symmetry (Duty Cycle) or Tri-state functionality. * **R:** Indicates **RoHS Compliance** (Lead-free). --- ### 3. Key Features * **Tight Stability:** Designed to maintain a consistent frequency even when the ambient temperature fluctuates. * **Low Phase Noise:** Crucial for RF applications to prevent signal interference and ensure clear data transmission. * **Rugged Construction:** Usually housed in a hermetically sealed metal package to protect against electromagnetic interference (EMI) and moisture. --- ### 4. Typical Applications These parts are found in professional-grade hardware rather than consumer electronics: 1. **Telecommunications:** Base stations, small cells, and backhaul equipment. 2. **Test & Measurement:** Oscilloscopes, signal generators, and frequency counters. 3. **Networking:** High-speed routers and switches requiring precise clocking for data synchronization. 4. **Military/Aerospace:** Guidance systems and secure communication links. --- ### 5. Circuit Integration Example When designing a PCB for this part, a bypass capacitor is essential to ensure power stability. ```c // Schematic Note for MHO+65TDD-R [Pin 1] -> NC or Tri-state Control [Pin 7] -> Ground (GND) [Pin 8] -> Output Signal (to CPU/FPGA Clock Input) [Pin 14] -> Vcc (+3.3V or +5.0V) // Place a 0.01uF to 0.1uF Ceramic Capacitor between Pin 14 and Pin 7. ```
