It belongs to a series of clock oscillators designed for applications requiring high stability, low jitter, and specific voltage levels. --- ### 1. Technical Specifications Below is a breakdown of the typical technical characteristics found in this specific part number series: | Parameter | Specification Details | | :--- | :--- | | **Component Type** | Fixed Frequency Crystal Oscillator (XO) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage (Vcc)** | Usually +5.0V or +3.3V (Specific to the "6" code) | | **Package Style** | 14-pin DIP (DIL) Metal Can (usually 4 pins connected) | | **Frequency Range** | Typically 1.0 MHz to 150.0 MHz | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Stability** | ±50ppm to ±100ppm (Standard) | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the "MHO" series follows a standard naming convention: * **MHO:** Series designation (Metal Hollow Oscillator / DIP package). * **+:** Lead-free / RoHS compliant indicator. * **6:** Denotes the input voltage (commonly 3.3V or 5V depending on the specific datasheet revision). * **8:** Denotes frequency stability (e.g., ±50ppm or ±100ppm). * **T:** Operating temperature range (T usually refers to Industrial: -40°C to +85°C). * **CD:** Symmetry/Duty Cycle requirements (typically 40/60% or 45/55%). * **R:** Packaging suffix (e.g., Tape & Reel or RoHS). --- ### 3. Key Electronic Features * **Tristate Functionality:** This part often includes a "Three-state" or "Enable/Disable" function on Pin 1. This allows the output to be disconnected electronically without powering down the device, useful for bus-oriented systems. * **Hermetically Sealed:** The metal "can" package is hermetically sealed to protect the quartz crystal from moisture and atmospheric contaminants, ensuring long-term frequency aging stability. * **Low Jitter:** Designed for high-speed data applications where timing precision is critical to reduce bit-error rates. --- ### 4. Application Areas These oscillators are commonly found in: 1. **Networking Hardware:** Hubs, routers, and switches. 2. **Industrial Control:** Programmable Logic Controllers (PLCs) and embedded systems. 3. **Test & Measurement:** Oscilloscopes and signal generators. 4. **Legacy Computing:** Motherboards or expansion cards requiring a 14-pin DIP footprint.
