Based on the part number **MHO+73TCD-R**, this component is a **Crystal Oscillator** manufactured by **Mercury Electronic**. It is a precision timing component used to provide a stable clock signal for digital circuits. --- ### Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Series** | MHO | Mercury High Output / Metal Can (Standard Type) | | **Package** | 7 | 14-pin DIP (Full size) or 8-pin DIP (Half size) equivalent footprint | | **Voltage** | 3 | 3.3V DC Operating Voltage | | **Output Type** | T | CMOS/TTL Compatible Output | | **Stability** | C | ±50 ppm (Parts Per Million) Frequency Stability | | **Duty Cycle** | D | 40% to 60% (Standard Symmetry) | | **RoHS** | -R | RoHS Compliant (Lead-free) | --- ### Key Electronic Characteristics #### 1. Frequency Control This device uses a quartz crystal resonator combined with an oscillation circuit to generate a square wave. The "C" rating indicates that the frequency will not deviate more than 50 parts per million across its rated temperature range. #### 2. Power Requirements * **Operating Voltage ($V_{DD}$):** 3.3V $\pm$ 10%. * **Current Consumption:** Typically ranges from 10mA to 30mA depending on the specific frequency (higher frequencies draw more current). #### 3. Output Waveform The "T" designation indicates **CMOS** logic levels: * **Logic High ($V_{OH}$):** Minimum 90% of $V_{DD}$. * **Logic Low ($V_{OL}$):** Maximum 10% of $V_{DD}$. * **Rise/Fall Time:** Fast switching (typically < 5ns) to ensure signal integrity in high-speed digital systems. --- ### Common Applications The MHO series is often used in legacy industrial equipment and specific communication hardware where a through-hole (DIP) mounting is preferred over Surface Mount (SMD) for durability or prototyping: * Microprocessor clocking. * Embedded systems controllers. * Networking equipment (Routers/Switches). * Test and Measurement instrumentation. --- ### Pin Configuration (Standard 14-pin DIP style) | Pin Number | Function | | :--- | :--- | | **Pin 1** | No Connection (NC) or Tri-state Control | | **Pin 7** | Ground (Case) | | **Pin 8** | Output Signal | | **Pin 14** | Supply Voltage ($V_{CC}$) |
