The **MHO+14TGD-R** is a specific series of **Crystal Oscillators** (Frequency Control components) manufactured by **MtronPTI**. These are high-reliability components typically used in industrial and telecommunications applications. --- ### 1. Technical Specifications Table Based on the part numbering nomenclature for the MHO series, here are the primary technical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | Fixed frequency clock source. | | **Package / Case** | 14-pin DIP (Full Size) | Through-hole metal canister. | | **Output Type** | HCMOS / TTL | Compatible with high-speed CMOS and standard TTL logic. | | **Supply Voltage** | 5.0 VDC | Standard operating voltage for the MHO+ series. | | **Frequency Range** | 1.0 MHz to 150.0 MHz | Specific frequency is usually laser-marked on the top. | | **Operating Temp** | -40°C to +85°C | Industrial temperature range (denoted by "G"). | | **Stability** | ±100 ppm | Standard frequency stability (typical for "D" code). | | **RoHS Status** | Compliant | Denoted by the "R" suffix. | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the component's construction: * **MHO+**: Refers to the product series (5.0V Full-size DIL Crystal Oscillator). * **14**: Indicates the package style (14-pin DIP footprint, though usually only 4 pins are present: Case Ground, Output, Supply, and NC/Enable). * **T**: Specifies the Output Load/Logic (HCMOS/TTL). * **G**: Specifies the Operating Temperature Range (-40°C to +85°C). * **D**: Specifies the Frequency Stability (Commonly ±100ppm, though this can vary by manufacturer datasheet revision). * **R**: Indicates **RoHS Compliance** (Lead-free). --- ### 3. Pin Configuration (Typical 14-pin DIP) While the package has the physical dimensions of a 14-pin integrated circuit, it typically only utilizes four active pins: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable. | | **7** | GND | Circuit and Case Ground. | | **8** | Output | The generated clock signal. | | **14** | +Vcc | +5.0V Power Supply. | --- ### 4. Common Applications * **Networking Hardware:** Routers, switches, and hubs requiring a stable clock. * **Industrial Controllers:** PLC (Programmable Logic Controllers) and automation equipment. * **Legacy Computing:** Replacement parts for older motherboards or timing circuits requiring 5V logic. * **Test & Measurement:** Oscilloscopes and signal generators. ---
