Key Technical Specifications Below is a breakdown of the typical electronic characteristics for this part series: | Feature | Specification (Typical) | | :--- | :--- | | **Part Type** | Crystal Oscillator (XO) | | **Package Type** | 4-Pin Through-Hole (DIP-14 or Half-Size DIP) | | **Supply Voltage ($V_{dd}$)** | 5.0V DC (Standard for the + series) | | **Output Type** | HCMOS/TTL Compatible | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±50 ppm to ±100 ppm (Typical) | | **Termination** | Sn/Pb or RoHS Compliant (R suffix indicates RoHS) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the specific electronic attributes: * **MHO**: Represents the Series/Manufacturer code (typically Mtron High-Output/Metal High-Reliability). * **+**: Usually denotes a specific voltage or specialized performance enhancement (e.g., 5.0V operation). * **6**: Refers to the Package Style (often 14-pin DIP footprint, though only 4 pins are active). * **2**: Stability code (e.g., ±50ppm). * **T**: Operating Temperature range code (e.g., Industrial -40/+85°C). * **B**: Duty Cycle specification (e.g., 40/60% or 45/55%). * **D**: Output Type (HCMOS/TTL). * **R**: **RoHS Compliant**. This indicates the part is lead-free and meets environmental safety standards. --- ### 3. Internal Components and Function The MHO+62TBD-R consists of several internal electronic stages: 1. **Quartz Crystal Blank**: The mechanical vibrating element that determines the fundamental frequency. 2. **Oscillator IC**: An integrated circuit that provides the gain to sustain oscillation. 3. **Buffer/Driver**: Converts the internal sine wave into a clean square wave (HCMOS/TTL) to drive other digital components on a PCB. 4. **Bypass Capacitors**: Built-in filtering to reduce power supply noise and jitter. --- ### 4. Common Applications Due to its robust through-hole design, it is frequently used in: * **Industrial Control Systems**: PLCs and automation hardware. * **Legacy Computing**: Replacing clock sources in older motherboard architectures. * **Telecommunications**: Base stations and networking hardware requiring 5V logic. * **Test & Measurement**: Signal generators and frequency counters.
