The **MHO+54FAAD-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, often manufactured by companies like MtronPTI. These components are critical for providing a stable clock signal in electronic circuits. --- ### 1. Technical Specifications Below are the general specifications for this class of oscillator (MHO series): | Feature | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package / Case** | 14-pin DIP (often with 4 pins connected) | | **Output Type** | CMOS / TTL Compatible | | **Voltage Supply** | Typically 5.0V (Standard for MHO series) | | **Frequency Stability** | Usually ±50ppm or ±100ppm | | **Operating Temperature** | -40°C to +85°C (Industrial) or 0°C to 70°C (Commercial) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number While manufacturers have specific coding schemes, the alphanumeric string generally breaks down as follows: * **MHO:** Series designation (Metal thru-hole, high-speed CMOS/TTL). * **+:** Often indicates lead-free/RoHS compliance or a specific voltage variant. * **54:** Usually refers to the physical package size and pin configuration (e.g., Half-size or Full-size DIP). * **FAAD:** Internal manufacturer codes for frequency stability, duty cycle, and operating temperature range. * **-R:** Indicates **RoHS Compliant** (Restriction of Hazardous Substances). --- ### 3. Pin Configuration For a standard 14-pin DIP package (where only 4 pins are functional), the layout is typically: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock frequency signal | | **14** | Vcc | Positive Power Supply (+5V) | --- ### 4. Common Applications * **Microprocessors:** Providing the fundamental heartbeat for CPUs. * **Networking:** Synchronizing data transmission in Ethernet switches or routers. * **Industrial Control:** Timing for PLCs and embedded controllers. * **Legacy Systems:** Often used as replacements in older computing hardware due to the DIP form factor.
