The **MHO+62TCD-R** is a high-precision, temperature-compensated crystal oscillator (TCXO) typically manufactured by companies like **MtronPTI**. This specific series is designed for applications requiring high stability and low phase noise in demanding environments. --- ### 1. Key Technical Specifications Below is a breakdown of the typical electronic characteristics for the MHO+62 series: | Parameter | Typical Value / Range | | :--- | :--- | | **Output Type** | CMOS / HCMOS | | **Supply Voltage (Vcc)** | 3.3V (standard for TCD variants) | | **Frequency Stability** | ±1.0ppm to ±5.0ppm (Over temp range) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Package Type** | 5x7mm Surface Mount (SMD) | | **Pin Count** | 4 or 6 Pins (depending on Enable/Disable config) | --- ### 2. Part Number Breakdown The alphanumeric code describes the specific features of the component: * **MHO+**: Refers to the specific product series (High-reliability TCXO). * **6**: Usually denotes the package size (e.g., 5.0 x 7.0 mm). * **2**: Often represents the supply voltage (e.g., 3.3V). * **TCD**: Indicates the Temperature Compensation type and high-stability internal circuitry. * **R**: Generally signifies **RoHS Compliance** (Lead-free). --- ### 3. Electronic Functionality The device consists of three primary internal stages: 1. **Crystal Resonator:** A precision-cut quartz crystal that provides the base resonant frequency. 2. **Compensation Network:** An analog or digital circuit that senses temperature changes and adjusts a varactor diode to pull the crystal frequency back to its nominal value, counteracting thermal drift. 3. **Output Buffer:** A CMOS driver that ensures the signal can drive the clock input of a Microprocessor or FPGA without signal degradation. --- ### 4. Common Applications Due to its stability, the MHO+62TCD-R is commonly used in: * **Telecommunications:** Base stations and small cells. * **GPS/Navigation:** Ensuring precise timing for satellite synchronization. * **Networking:** Ethernet switches and routers requiring low jitter. * **Test & Measurement:** Portable diagnostic equipment.
