The **MHO+34FAD-R** is a specific type of **Crystal Oscillator** (often categorized under Frequency Control products). It is a high-precision electronic component used to generate a stable clock signal for digital circuits. --- ### 1. General Specifications The part number typically follows the naming convention of manufacturers like **MtronPTI**. Below are the technical characteristics associated with this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package / Case** | 14-pin DIP (DIL) - Often 4 pins connected | | **Frequency Range** | Typically 1.000 MHz to 150.000 MHz | | **Supply Voltage (Vcc)** | +5.0 VDC (Standard for the 'H' series) | | **Output Type** | CMOS / TTL Compatible | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the '-R' suffix) | --- ### 2. Breakdown of the Part Number To understand the electronic properties, we can decode the nomenclature: * **MHO**: Represents the product series (Metal Half-size or Full-size Crystal Oscillator, usually in a 14-pin or 8-pin DIP metal package). * **+**: Often indicates a specific revision or lead-free process enhancement. * **3**: Usually denotes the Stability (e.g., ±50 ppm or ±100 ppm depending on the datasheet version). * **4**: Refers to the Duty Cycle (typically 40/60% or 45/55%). * **F**: Temperature Range code (F usually denotes -40°C to +85°C). * **AD**: Internal manufacturer codes for specific output logic or frequency calibration. * **-R**: **RoHS Compliant**. This confirms the part is manufactured without hazardous substances like lead. --- ### 3. Pin Configuration (Typical 14-pin DIP) Though it has the footprint of a 14-pin integrated circuit, usually only 4 pins are functional: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / Tri-state | No connection or Output Enable/Disable | | **7** | GND | Ground connection | | **8** | Output | The generated clock signal (Square wave) | | **14** | Vcc | Power supply (+5.0V) | --- ### 4. Typical Applications * **Microprocessors:** Providing the "heartbeat" for CPUs and Microcontrollers. * **Networking:** Timing for Ethernet controllers and routers. * **Industrial Control:** Used in PLC (Programmable Logic Controllers) where temperature stability is required. * **Legacy Systems:** Found in older telecommunications and computing hardware due to the DIP package style.
