The **MHO+65FCD-R** is a high-precision, temperature-compensated crystal oscillator (TCXO) or clock oscillator module, typically manufactured by companies like **MtronPTI**. This specific series is designed for applications requiring high stability and reliability in harsh or demanding environments. --- ### 1. Component Specifications The part number "MHO+65FCD-R" can be broken down into specific technical parameters based on standard naming conventions for the MHO series: | Parameter | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) / TCXO | | **Package Style** | 14-pin DIP (Dual In-line Package) or Half-size DIP | | **Operating Voltage** | Typically 5.0V or 3.3V (Model dependent) | | **Output Type** | CMOS / TTL Compatible | | **RoHS Status** | "-R" suffix indicates Lead-Free / RoHS Compliant | | **Stability** | High precision (often within ±50ppm or better) | --- ### 2. Key Internal Electronic Parts The internal architecture of this module consists of several integrated electronic stages: 1. **Quartz Crystal Blank:** The heart of the component, providing the fundamental frequency through the piezoelectric effect. 2. **Oscillator Circuitry:** Transistors and capacitors that maintain the oscillation of the crystal. 3. **Buffer Amplifier:** Ensures the output signal is strong enough to drive external loads (CMOS/TTL) without affecting the internal frequency. 4. **Temperature Compensation (Optional):** Many MHO series parts include thermistors and varactors to adjust the frequency based on ambient temperature changes. --- ### 3. Pinout Configuration While you should always consult the specific datasheet for your batch, the standard 14-pin DIP oscillator configuration is: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | N/C or Tri-state | No connection or Output Enable/Disable | | **Pin 7** | GND | Circuit ground | | **Pin 8** | Output | The generated clock signal (Square Wave) | | **Pin 14** | Vcc | Positive Power Supply | --- ### 4. Applications Due to its robust DIP packaging and stability, the MHO+65FCD-R is commonly used in: * **Industrial Control Systems:** For timing in PLC and automation hardware. * **Legacy Computing:** Replacement parts for older motherboards or timing circuits. * **Test & Measurement:** Providing a stable reference clock for oscilloscopes or frequency counters.
