The **MHO+62TDD-R** is a high-performance, precision Crystal Oscillator (XO) typically used in telecommunications and data networking equipment. It is manufactured by **MtronPTI**, a company specializing in frequency control and spectrum control solutions. --- ### 1. Technical Specifications The following table highlights the core electronic characteristics of the MHO+62TDD-R series: | Parameter | Specification Details | | :--- | :--- | | **Frequency Range** | Typically ranges from 1.0 MHz to 100+ MHz (specific to ordering) | | **Output Type** | CMOS / TTL Compatible | | **Operating Voltage** | 5.0V (Standard for the "6" series designation) | | **Stability** | $\pm$25ppm to $\pm$100ppm (depends on specific sub-code) | | **Package Style** | 14-pin DIP (Dual In-line Package) compatible | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Enable/Disable Function** | Included (Tri-state functionality) | --- ### 2. Breakdown of the Part Number Electronic components often use a "smart" numbering system. For MtronPTI, the code breaks down as follows: * **MHO:** Identifies the series (Metal Hermetic Oscillator). * **6:** Indicates the input voltage (5.0 Volts). * **2:** Usually indicates the frequency stability (e.g., $\pm$50ppm). * **T:** Denotes "Tri-state" capability (the output can be disconnected/high-impedance). * **DD:** Refers to the temperature range and symmetry/duty cycle requirements. * **R:** Indicates **RoHS compliance** (Lead-free). --- ### 3. Key Electronic Functions The MHO+62TDD-R serves three primary roles within a circuit: 1. **Clock Generation:** It provides a stable, periodic square wave signal that acts as the "heartbeat" for microprocessors, FPGAs, and Digital Signal Processors (DSPs). 2. **Tri-State Output:** The "T" in the part number allows the output pin to enter a high-impedance state. This is useful for testing or when multiple oscillators share a single bus. 3. **Hermetic Sealing:** Because it is a metal-can package (DIP-14), the internal quartz crystal is protected from atmospheric moisture and contaminants, ensuring long-term frequency aging stability. --- ### 4. Typical Application Circuit When integrating this part, designers typically follow this basic layout: ```c // Pin Configuration (Top View) Pin 1: Tri-state Control (High = Output, Low = High-Z) Pin 7: Ground (GND) Pin 8: Output Signal (Frequency) Pin 14: Vcc (+5.0V Supply) // Design Note: // Always place a 0.01uF to 0.1uF ceramic bypass capacitor // as close to Pin 14 as possible to reduce noise. ```
