The **MHO+65TAG-R** is a high-precision, industrial-grade **Oven Controlled Crystal Oscillator (OCXO)** manufactured by MtronPTI. These components are designed for applications requiring extreme frequency stability over a wide range of temperatures. --- ## 1. Core Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | OCXO (Oven Controlled Crystal Oscillator) | | **Output Frequency** | Custom (Commonly 10MHz to 100MHz) | | **Supply Voltage** | +5.0 VDC (Standard) | | **Package Type** | DIP-14 (Plug-in) or Surface Mount Options | | **Output Waveform** | HCMOS / ACMOS | | **Operating Temp Range** | -40°C to +85°C | --- ## 2. Key Electronic Features ### A. Oven Control Mechanism The "Oven" in OCXO refers to an internal heating element and a thermistor-controlled circuit. This circuit maintains the quartz crystal at a constant, specific temperature (the "turnover point"), which prevents frequency drift caused by external temperature fluctuations. ### B. Frequency Stability Unlike standard oscillators (XO) or temperature-compensated oscillators (TCXO), the MHO+65TAG-R offers stability in the **parts per billion (ppb)** range. This is critical for timing synchronization in telecommunications. ### C. Low Phase Noise This part is engineered to have minimal "jitter" or phase noise, ensuring that the clock signal is clean and does not introduce errors into high-speed data transmission systems. --- ## 3. Typical Applications * **Base Stations:** Used in 4G/5G cellular infrastructure for timing. * **Test & Measurement:** Internal clocks for oscilloscopes and frequency counters. * **Satellite Communications:** Ground station synchronization. * **Network Switches:** Maintaining Synchronous Ethernet (SyncE) standards. --- ## 4.
