The **MHO+47TDD-R** is a specific type of **Crystal Oscillator (XO)**. It is a precision electronic component used to create an electrical signal with a very precise frequency. ### 1. Technical Specifications The part number follows a specific nomenclature used by manufacturers like **MtronPTI**. Below are the typical characteristics associated with this series: | Parameter | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (Fixed Frequency) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full Size | | **Operating Voltage** | Typically 5.0V DC | | **Output Type** | TTL / HCMOS Compatible | | **Frequency Range** | Usually ranges between 1.0 MHz to 100.0 MHz (Specific to the label) | | **Frequency Stability** | Usually ±50ppm or ±100ppm (depending on the exact sub-grade) | | **Operating Temp** | 0°C to +70°C (Standard Commercial) | --- ### 2. Part Number Breakdown While manufacturer codes can vary slightly, here is the standard breakdown for the MHO series: * **MHO:** Identifies the product series (Metal package, Thru-hole, 5V). * **+ (Plus Sign):** Usually indicates RoHS compliance (Lead-free). * **47:** This code typically refers to the frequency stability and duty cycle (e.g., 45/55% symmetry). * **TDD:** This represents the specific package configuration and functional options (like Tri-state enable/disable). * **R:** Indicates RoHS compliance or Tape & Reel packaging (though rare for DIP packages). --- ### 3. Pin Configuration (14-pin DIP) Though it occupies the space of a 14-pin IC, only 4 pins are usually present: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | N/C or Tri-state | No connection or Output Enable/Disable | | **Pin 7** | GND | Case and Circuit Ground | | **Pin 8** | Output | The generated clock signal | | **Pin 14** | Vcc | +5.0V Power Supply | --- ### 4. Common Applications These oscillators are "legacy" style components often found in: * **Industrial Control Systems:** For timing logic in older PLC hardware. * **Telecommunications:** Providing reference clocks for data transmission. * **Embedded Systems:** Used on motherboards or expansion cards requiring a stable 5V clock source. * **Legacy Computing:** Replacement parts for vintage computer repairs. ---
