The **MCSO2FV/CE** is a high-reliability, low-voltage CMOS clock oscillator specifically designed for harsh environments, primarily in aerospace, defense, and high-end industrial applications. It is manufactured by **Microchip (formerly Vectron/Micro Crystal technology)**. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 10 kHz to 225 MHz | | **Supply Voltage (Vdd)** | +1.8 V to +3.3 V | | **Output Type** | CMOS / HC-MOS | | **Package Type** | Ceramic SMD (Standard 4-pad) | | **Dimensions** | 3.2 x 2.5 x 1.0 mm | | **Operating Temperature** | -55°C to +125°C (Military Grade) | | **Aging** | ±3 ppm max (first year) | --- ### 2. Core Features and Benefits * **Extreme Durability:** These oscillators are built to withstand high shock (up to 5000g) and vibration, making them ideal for projectiles or aerospace telemetry. * **Low Power Consumption:** Optimized for battery-operated systems or low-voltage FPGA/Microcontroller circuits. * **Wide Frequency Stability:** Offers tight stability across the entire military temperature range, often essential for precise timing in communication protocols. * **Hermetically Sealed:** The ceramic package is vacuum-sealed to prevent aging caused by environmental moisture or gases. --- ### 3. Pin Configuration The MCSO2FV/CE follows the standard 4-pin layout for SMD oscillators: 1. **Pin 1 (E/D):** Enable/Disable (Tristate) function. Applying a logic low puts the output into high impedance. 2. **Pin 2 (GND):** Ground connection. 3. **Pin 3 (Output):** The CMOS clock signal output. 4. **Pin 4 (Vdd):** DC Supply Voltage. --- ### 4. Typical Applications * **Aerospace & Defense:** Navigation systems, flight control computers, and secure communications. * **Downhole Drilling:** Geothermal or oil/gas exploration tools where high temperatures are present. * **Medical Electronics:** Implantable or diagnostic devices requiring high reliability in a small form factor. * **High-End Networking:** Synchronizing data transfers in harsh industrial environments.
