The **MHO+47TCG-R** is a specific type of **Crystal Oscillator** manufactured by MtronPTI. It is a high-precision frequency control component used to generate a stable clock signal for electronic circuits. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | Active oscillator providing a CMOS output. | | **Package Style** | 14-pin DIP (Full size) | A through-hole metal canister package. | | **Voltage Supply** | 5.0 VDC | Standard operating voltage for the internal circuitry. | | **Output Type** | CMOS / TTL | Compatible with standard digital logic levels. | | **Frequency Stability** | ±100 ppm (Typical for '47') | The deviation from nominal frequency over temperature. | | **Temperature Range** | 0°C to +70°C | Standard commercial operating temperature range. | | **RoHS Status** | Compliant (-R suffix) | Manufactured without hazardous substances (Lead-free). | --- ### 2. Internal Electronic Components Inside the metal "MHO" canister, the device consists of several integrated parts: 1. **AT-Cut Quartz Crystal:** The physical heart of the component that vibrates at a specific frequency when a voltage is applied. 2. **Oscillator IC:** An integrated circuit that provides the gain needed to sustain oscillation and buffers the output signal. 3. **Bypass Capacitor:** Internal capacitance to filter power supply noise and ensure signal integrity. 4. **Metal Housing:** A hermetically sealed metal case that provides electromagnetic interference (EMI) shielding and protects the crystal from moisture. --- ### 3. Pin Configuration (Full-Size DIP) Though it has a 14-pin footprint, usually only 4 pins are electrically connected: * **Pin 1:** N/C (No Connection) or Tri-state (Enable/Disable). * **Pin 7:** Case Ground (GND). * **Pin 8:** Output Signal (The clock frequency). * **Pin 14:** Supply Voltage (+5V). --- ### 4. Common Applications Due to its robust metal package and 5V operation, this part is frequently found in: * **Legacy Computing:** Motherboards and peripheral cards using TTL logic. * **Industrial Control:** PLCs and automation equipment requiring through-hole durability. * **Embedded Systems:** Providing the master clock for microcontrollers or FPGAs.
