### MHO362FCD-R: Technical Overview The **MHO362FCD-R** is a high-precision **Temperature Compensated Crystal Oscillator (TCXO)** manufactured by MtronPTI. These components are critical in telecommunications and navigation systems where frequency stability over varying temperatures is mandatory. --- ### Core Specifications | Feature | Specification Details | | :--- | :--- | | **Component Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Half Size | | **Output Waveform** | HCMOS / TTL Compatible | | **Frequency Range** | Typically 1.0 MHz to 160.0 MHz (model specific) | | **Supply Voltage (Vcc)** | +5.0 VDC (Standard) | | **Operating Temp Range** | -40°C to +85°C (Industrial Grade) | --- ### Key Electronic Attributes #### 1. Temperature Compensation Unlike standard crystal oscillators (XO), the "TC" in TCXO indicates an internal compensation network. It uses a thermistor-based circuit to adjust the voltage applied to the crystal, canceling out the frequency drift that normally occurs when the ambient temperature changes. #### 2. Output Logic (HCMOS/TTL) The `FCD` designation often refers to the output drive capability. It provides a square wave output that can interface directly with standard digital logic gates (High-speed CMOS or Transistor-Transistor Logic), making it ideal for driving microprocessors or FPGAs. #### 3. Stability and Precision * **Frequency Stability:** Typically ranges from ±1.0 ppm to ±5.0 ppm. * **Phase Noise:** Designed for low jitter, ensuring that the timing signals remain "clean" in high-speed data transmission. --- ### Pin Configuration (Typical 14-pin Half-Size) | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Vcon | No connection or Voltage Control (for VCTCXO variants) | | **7** | Case Ground | Connected to the metal cover for EMI shielding | | **8** | Output | The generated frequency signal | | **14** | Vcc | Positive power supply input (+5V) | --- ### Typical Applications * **Wireless Communication:** Base stations and point-to-point radio. * **GPS/GNSS:** Precise timing for satellite signal acquisition. * **Networking:** Synchronous Ethernet and high-speed routers. * **Test Equipment:** Frequency counters and signal generators.
