The part number **MHO+66FFG-R** refers to a specific series of high-performance **Crystal Oscillators**, typically manufactured by companies like MtronPTI. These components are critical for providing a stable clock signal in electronic circuits. --- ### 1. General Specifications This part is a **Clock Oscillator** designed for high-frequency stability. Below are the typical technical parameters associated with this series: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Output Type** | CMOS / TTL Compatible | | **Package Style** | 14-pin DIP (Dual In-line Package) or Half-Size DIP | | **Operating Voltage** | Generally 5.0V (Standard for MHO series) | | **Frequency Range** | 1.000 MHz to 100.000 MHz (Specific to exact sub-model) | | **RoHS Status** | Compliant (Indicated by the "R" suffix) | --- ### 2. Part Number Breakdown (Nomenclature) To understand the specific capabilities, we can decode the alphanumeric string: * **MHO**: Represents the Series (Metal Hermetic Package, 5.0V, CMOS/TTL). * **+**: Usually denotes a specific lead-free or environmental compliance marker. * **66**: This typically refers to the **Frequency Stability** and **Operating Temperature Range**. In the MtronPTI system, "66" often indicates a stability of ±100ppm over -40°C to +85°C. * **F**: Refers to the **Duty Cycle** (typically 40/60% or 45/55%). * **F**: Refers to the **Tristate** function (Enable/Disable capability on Pin 1). * **G**: Denotes the **Package Type** (e.g., Gull-wing or specific pin configuration). * **-R**: Indicates **RoHS Compliance** (Lead-free). --- ### 3. Key Technical Features * **Hermetic Sealing:** The crystal is housed in a metal package that is resistance-welded to protect against moisture and atmospheric contaminants. * **Tristate Output:** Allows the output to be placed in a high-impedance state, which is useful for testing or for power-saving modes in complex bus architectures. * **Wide Temperature Range:** Designed to operate in "Industrial" environments (-40°C to +85°C), making it more robust than standard commercial grade parts. --- ### 4. Common Applications These oscillators are used in systems requiring a reliable "heartbeat": 1. **Networking Hardware:** Switches, routers, and modems. 2. **Industrial Controllers:** PLC (Programmable Logic Controllers) and automation sensors. 3. **Legacy Computing:** Motherboards or expansion cards requiring DIP-style clock sources. 4. **Embedded Systems:** Microcontrollers that require an external high-precision clock rather than an internal RC circuit.
