The **MHO+45FAAD-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, often manufactured by companies like **MtronPTI**. These components are critical for providing a stable clock signal in electronic circuits. Below is a detailed breakdown of its specifications and characteristics. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical behavior. While exact parameters can vary slightly by manufacturer series, here is the standard profile: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | An active oscillator that includes the crystal and the oscillation circuit. | | **Package / Case** | 14-pin DIP (Half-size) | Usually a 4-pin metal package that fits into a standard 14-pin DIP footprint. | | **Supply Voltage** | 5.0V DC | Operates on a standard 5-volt power rail. | | **Output Type** | CMOS / TTL | Provides a square wave output compatible with standard logic gates. | | **Stability** | ±100 ppm (Typical) | Frequency stability over the operating temperature range. | | **RoHS Status** | Compliant (-R) | The "R" suffix typically denotes Lead-Free/RoHS compliance. | --- ### 2. Pin Configuration For this "Half-size" DIP package, the pinout is generally standardized as follows: 1. **Pin 1 (NC or Tri-state):** No connection or an Enable/Disable function. 2. **Pin 7 (GND):** Connected to the system ground. 3. **Pin 8 (Output):** The clock signal output (Square Wave). 4. **Pin 14 (Vcc):** +5V Power supply. --- ### 3. Key Applications Because of its high stability and standard 5V operation, the MHO+45FAAD-R is used in: * **Legacy Computing:** Microprocessor clocking for older 8-bit or 16-bit systems. * **Industrial Controls:** Timing for PLCs and automation hardware. * **Networking:** Synchronizing data transmission in modems or routers. * **Test Equipment:** Providing a reference frequency for measuring devices. --- ### 4. Decoding the Part Number (General Breakdown) | Segment | Meaning | | :--- | :--- | | **MHO** | Series Identifier (Metal Clock Oscillator, Half-size). | | **+** | Positive Logic or Lead-free designation. | | **45** | Frequency Stability code (Often ±50ppm or ±100ppm). | | **F** | Temperature Range (e.g., 0°C to +70°C). | | **AA** | Frequency specific code or custom internal designation. | | **D** | Duty Cycle (e.g., 40/60% or 45/55%). | | **-R** | RoHS Compliant. | --- ### 5. Circuit Integration Example To use this part, you generally need a 0.01µF to 0.1µF decoupling capacitor placed close to the Vcc pin. ```c // Typical Connection Diagram [Vcc 5V] ----+---- [Pin 14] | [C1 0.1uF] | [GND] -------+---- [Pin 7] [Microcontroller] <--- [Pin 8 (Output)] ```
