The **MHO+33FCG-R** is a specific part number belonging to a series of **Crystal Clock Oscillators** manufactured by **MtronPTI**. These components are critical in electronic circuits for providing a stable, precise timing signal (clock pulse) required for microprocessors and digital logic. --- ## Technical Specifications | Parameter | Specification Details | | :--- | :--- | | **Manufacturer** | MtronPTI | | **Package Type** | 14-pin DIP (Dual In-line Package) - Half Size | | **Output Type** | CMOS / TTL Compatible | | **Voltage Supply** | Typically 3.3V or 5.0V (Series dependent) | | **Frequency Range** | Fixed frequency (Value varies by specific sub-marking) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ## Key Features ### 1. Stability and Precision Unlike simple ceramic resonators, the MHO series uses quartz crystal technology, which offers much higher frequency stability over a wide temperature range. ### 2. Hermetic Sealing The "MHO" series typically features a metal cold-welded package. This hermetic seal protects the internal quartz crystal from atmospheric moisture and contaminants, ensuring long-term reliability. ### 3. Integrated Circuitry This is an **active** oscillator. This means it contains both the quartz crystal and the necessary oscillation circuitry (capacitors/transistors) inside the metal can. You only need to provide power (Vcc) and Ground to receive a stable square wave output. --- ## Pin Configuration (Typical 4-pin Half-DIP) Even though it is in a 14-pin DIP footprint, typically only 4 pins are functional: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | NC / 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 | --- ## Suffix Breakdown: "MHO+33FCG-R" * **MHO:** Series designation (Metal Hermetic Oscillator). * **+:** Often indicates a specific revision or lead-free process. * **33:** Usually refers to the operating voltage (e.g., 3.3 Volts). * **F/C/G:** These characters represent internal codes for frequency stability (e.g., ±100ppm), operating temperature range, and duty cycle requirements. * **-R:** RoHS Compliant (Lead-free). ---
