The **MHO364FCD-R** is a specific electronic component, typically identified as a **high-precision, temperature-compensated crystal oscillator (TCXO)** or a specialized clock oscillator module. These parts are critical in telecommunications and data processing for maintaining stable frequency timing. --- ### 1. Technical Specifications The following table outlines the general technical characteristics associated with this series of components: | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (TCXO / Clock) | | **Package Type** | Surface Mount Device (SMD) | | **Output Type** | CMOS / TTL Compatible | | **Voltage Supply** | Usually 3.3V or 5.0V (Variant dependent) | | **Frequency Stability** | High (Temperature Compensated) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by -R suffix) | --- ### 2. Key Internal Electronic Parts The MHO364FCD-R is an integrated module rather than a discrete component. Its internal architecture consists of: 1. **Quartz Crystal Blank:** The heart of the component that vibrates at a specific frequency when voltage is applied. 2. **Compensation Circuitry:** An internal thermistor network or digital compensation IC that adjusts the frequency based on ambient temperature changes to prevent "drift." 3. **Output Buffer:** A transistor-based stage that ensures the signal is strong enough to drive the load of the main PCB without distorting the waveform. 4. **Varactor Diode:** Used in the tuning circuit to pull the frequency into the exact desired range. --- ### 3. Part Number Breakdown The nomenclature usually follows this logic: * **MHO:** Series designation (often refers to a specific package size or manufacturer line). * **364:** Frequency code or specific internal design iteration. * **FCD:** Functional characteristics (e.g., specific stability ppm or voltage requirements). * **-R:** Indicates **RoHS compliance** (Lead-free) or **Tape & Reel** packaging for automated assembly. --- ### 4. Typical Applications Because of its stability, this part is used in: * **Networking Hardware:** Routers, switches, and base stations. * **GPS Receivers:** Where precise timing is necessary for location accuracy. * **Embedded Systems:** Microcontrollers requiring a stable external clock source.
