Technical Specifications Below is a breakdown of the typical electronic characteristics for this component: | Feature | Specification | | :--- | :--- | | **Component Type** | Fixed Frequency Crystal Oscillator (XO) | | **Package Type** | 14-pin DIP (DIP-14), 4-pins used | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage (Vcc)** | +5.0 VDC (Standard) | | **Frequency Stability** | ±100 ppm (standard for "61" series) | | **Operating Temperature** | 0°C to +70°C (Commercial Grade) | | **RoHS Status** | Compliant (indicated by "-R") | --- ### 2. Pin Configuration (DIP-14 Style) Although the physical size matches a 14-pin integrated circuit, usually only 4 pins are functional: 1. **Pin 1 (NC/ED):** No Connection or Output Enable/Disable (Tri-state). 2. **Pin 7 (GND):** Case Ground and Circuit Return. 3. **Pin 8 (Output):** The generated clock frequency signal. 4. **Pin 14 (Vcc):** +5V Power Supply. --- ### 3. Key Features and Applications * **Full-Size Metal Can:** The "MHO" designation refers to the large, through-hole metal package which provides excellent EMI shielding. * **TBD Designation:** In the MtronPTI nomenclature, "T" often signifies a specific temperature range or stability variation, while "BD" refers to the specific output load drive capability (usually 15pF to 50pF). * **Stability:** It provides a reliable heartbeat for digital systems, ensuring that data is processed at the correct intervals. #### Common Uses: * Network Switches and Routers. * Legacy Industrial Control Systems. * Microprocessor Clocking. * Test and Measurement Equipment. --- ### 4.
