The **MHO+57FBG-R** is a high-precision, high-frequency **TCXO (Temperature Compensated Crystal Oscillator)** manufactured by MtronPTI. These components are designed for applications requiring extreme frequency stability over a wide temperature range. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of the MHO+ series oscillators: | Parameter | Typical Value / Specification | | :--- | :--- | | **Component Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage (Vcc)** | +5.0 VDC (Standard) | | **Frequency Range** | Typically 1.0 MHz to 160.0 MHz | | **Stability vs. Temperature** | ±1.0 ppm to ±5.0 ppm (varies by sub-model) | | **Package Style** | 14-pin DIP (Full size, 4 pins connected) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | "R" suffix indicates RoHS Compliance | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the component's construction: * **MHO:** Identifies the product series (MtronPTI High-Frequency Oscillators). * **+:** Usually indicates a specific voltage or custom modification. * **5:** Represents the supply voltage (5.0V). * **7:** Refers to the frequency stability/temperature range code. * **FB:** Refers to the output waveform and symmetry (e.g., HCMOS). * **G:** Indicates the "G" package style (14-pin DIP through-hole). * **-R:** Denotes **RoHS Compliant** (Lead-free). --- ### 3. Electronic Functional Blocks Internally, this device consists of three main stages: 1. **Quartz Crystal Resonator:** The core element that provides the base resonant frequency. 2. **Compensation Network:** A temperature sensor and a varactor diode. As temperature changes, the sensor adjusts the voltage to the diode, shifting the capacitance to keep the crystal on the target frequency. 3. **Output Buffer:** An HCMOS/TTL driver that ensures the signal can drive downstream integrated circuits without degrading the waveform. --- ### 4. Common Applications Due to its stability and through-hole design, the MHO+57FBG-R is commonly found in: * **Telecommunications:** Base stations and wireless backhaul. * **Test & Measurement:** Frequency counters and signal generators. * **Legacy Systems:** Industrial control boards requiring high-reliability timing. * **RF Modules:** Local oscillators for radio transceivers. ---
