The part number **MHO+46FFD-R** refers to a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. These components are critical for providing a precise timing reference (clock signal) in electronic circuits. --- ## 1. Technical Specifications The alphanumeric code provides specific details regarding the oscillator's physical and electrical characteristics. Below is a breakdown of its core parameters: | Parameter | Specification | | :--- | :--- | | **Output Type** | CMOS / TTL Compatible | | **Package Style** | 14-pin DIP (Dual In-line Package) | | **Input Voltage ($V_{cc}$)** | Typically 5.0V (Standard for MHO series) | | **Frequency Range** | 1.0 MHz to 160.0 MHz (Varies by specific sub-model) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Stability** | ±100ppm to ±25ppm (Depending on exact suffix) | | **RoHS Status** | Compliant (Indicated by the **-R** suffix) | --- ## 2. Key Features and Construction ### Mechanical Design * **Hermetic Seal:** The crystal is housed in a metal "Full-Size" 14-pin DIP package, which is vacuum-sealed or filled with inert gas to prevent environmental contamination and aging. * **Through-Hole Mounting:** Designed for traditional PCB mounting where pins are inserted through holes and soldered. ### Electrical Performance * **Low Phase Jitter:** These oscillators are designed for high-speed data applications where timing precision is vital to prevent data errors. * **Tristate Functionality:** Many models in this series include an "Enable/Disable" function (Pin 1), allowing the output to be turned off to save power or perform system testing. --- ## 3. Applications The MHO series is commonly found in legacy industrial systems and high-reliability communication hardware: 1. **Networking Equipment:** Providing clock signals for routers, switches, and modems. 2. **Industrial Controllers:** Used in PLCs (Programmable Logic Controllers) where temperature stability is necessary. 3. **Data Acquisition:** Timing for Analog-to-Digital converters in measurement devices. 4. **Legacy Computing:** Replacement parts for older motherboards or embedded systems using through-hole technology. --- ## 4. Part Number Breakdown (Prefix Analysis) * **MHO:** Identifies the product series (MtronPTI High-speed Oscillator). * **46:** Usually denotes the specific package height and voltage configuration. * **FF:** Often refers to frequency stability and temperature range (Fixed Frequency). * **D:** Often indicates the "Tristate" (Duty cycle/Disable) capability. * **-R:** Indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards (Lead-free).
