The **MHO+52FGD-R** is a specific model within the series of high-precision, temperature-compensated crystal oscillators (TCXO) or clock oscillators, typically manufactured by companies like **MtronPTI**. These components are designed for high-reliability applications where frequency stability is critical over a wide temperature range. --- ### 1. Technical Specifications | Parameter | Specification (Typical) | | :--- | :--- | | **Package Type** | 5.0 x 7.0 mm Surface Mount Device (SMD) | | **Output Type** | CMOS / HCMOS | | **Operating Voltage** | 3.3V (standard for the 'G' designation) | | **Frequency Stability** | Highly stable (often ±20ppm to ±100ppm depending on suffix) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by the 'R' suffix) | --- ### 2. Part Number Breakdown The alphanumeric code follows a specific nomenclature that defines the part's physical and electrical characteristics: * **MHO**: Represents the series (Mtron High-Output/Oscillator series). * **+**: Often indicates a specific RoHS compliance or lead-free manufacturing process. * **5**: Refers to the package size/style (5x7mm 4-pad). * **2**: Usually denotes the supply voltage (e.g., 2 = 3.3V, 3 = 5V). * **FGD**: These characters represent the specific internal circuitry, frequency stability, and symmetry (Duty Cycle). * **R**: Indicates the part is **RoHS Compliant**. --- ### 3. Key Electronic Features #### Frequency Control The device uses a quartz crystal resonator combined with an integrated circuit to provide a stable clock signal. Unlike a simple crystal, this "oscillator" includes the necessary capacitors and transistors to generate the waveform internally. #### Signal Integrity (HCMOS) The **HCMOS output** ensures compatibility with most modern microcontrollers (MCUs) and FPGAs. It provides: 1. High noise immunity. 2. Low power consumption. 3. Fast rise and fall times, suitable for high-speed digital logic. #### Tri-state Functionality Most models in this series include a "Tri-state" or "Enable/Disable" pin (usually Pin 1). When the pin is pulled low, the output goes into a high-impedance state, allowing for power saving and easier testing on a PCB. --- ### 4. Typical Applications * **Networking**: Ethernet switches and routers. * **Telecommunications**: Base stations and optical line terminals. * **Embedded Systems**: Providing the master clock for industrial computers. * **Storage**: Fiber Channel and SAN equipment.
