The **MHO+45TGG-R** is a high-precision, high-frequency crystal oscillator. It belongs to the MHO series, which is known for its reliability in industrial and telecommunications applications. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its electrical characteristics: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Part Series** | MHO+ | High-speed CMOS/TTL compatible | | **Package Type** | 14-pin DIP | Through-hole, hermetically sealed metal can | | **Frequency Range** | Typically 1.0 MHz to 100 MHz | Precise frequency depends on sub-marking | | **Supply Voltage (Vcc)** | 5.0V DC | Standard logic level power | | **Stability** | ±50 ppm to ±100 ppm | Operating over the specified temperature range | | **Output Type** | HCMOS / TTL | Square wave output | | **RoHS Status** | Compliant (-R) | Lead-free construction | --- ### 2. Functional Description The device is an **Active Crystal Oscillator**. Unlike a passive crystal (which requires external capacitors and an inverter circuit), this component integrates the quartz crystal and the oscillation circuitry into a single shielded package. #### Internal Components: * **Quartz Crystal Resonator:** The heart of the unit, providing the stable reference frequency. * **Oscillator IC:** A low-power CMOS chip that drives the crystal and buffers the output. * **Bypass Capacitor:** Often integrated internally to reduce power supply noise. * **Metal Housing:** Provides EMI (Electromagnetic Interference) shielding to prevent the clock signal from interfering with other components. --- ### 3. Pin Configuration The MHO+ series typically utilizes a standard 4-pin layout within a 14-pin DIP footprint: | Pin Number | Function | Description | | :--- | :---: | :--- | | **Pin 1** | NC or E/D | No connection or Enable/Disable (Tristate) | | **Pin 7** | GND | Circuit Ground | | **Pin 8** | Output | The generated clock signal (Square Wave) | | **Pin 14** | Vcc | +5.0V Power Supply | --- ### 4. Applications The MHO+45TGG-R is designed for systems requiring a robust, stable clock source: * **Legacy Computing:** Motherboards and peripheral controllers. * **Telecommunications:** Network switches and synchronization modules. * **Industrial Control:** PLCs and automation hardware. * **Test Equipment:** Signal generators and counters. ---
