The **MHO+53TBD-R** is a specific series and model designation for a high-performance **Crystal Oscillator**, typically manufactured by companies like MtronPTI. These components are essential in electronic circuits for generating stable clock signals. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its electrical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Dual In-line Package) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage** | Typically 5.0V (indicated by the '5' in the prefix) | | **Stability** | Usually ±50ppm or ±100ppm (depending on the full suffix) | | **Operating Temperature** | Standard Industrial ranges (e.g., 0°C to +70°C) | --- ### 2. Functional Description The MHO+53TBD-R acts as the "heartbeat" of a digital system. It combines a quartz crystal and an integrated circuit (IC) inside a hermetically sealed metal package. * **Internal Circuitry:** It includes a Pierce oscillator circuit and an output buffer. * **Tri-state Function (T):** The "T" in the part number often indicates a **Tri-state (Enable/Disable)** function on Pin 1. This allows the output to be turned off (high impedance) to save power or perform testing. * **RoHS Compliance (R):** The "-R" suffix denotes that the part is Lead-Free and RoHS compliant, meeting modern environmental standards. --- ### 3. Pin Configuration For the standard 14-pin DIP footprint (though only 4 pins are usually present): | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable (Tri-state) or No Connect | | **7** | GND | Circuit Ground | | **8** | Output | The generated square wave (clock signal) | | **14** | Vcc | Positive Supply Voltage (+5V) | --- ### 4. Common Applications Due to its robust DIP packaging and 5V operation, this part is frequently found in: * Legacy computing hardware. * Industrial control systems (PLCs). * Embedded systems requiring a stable 5V clock source. * Telecommunications equipment. ---
