The **F2TS-80-R/Q** is a high-performance, programmable crystal oscillator (SPXO) typically associated with timing and frequency control applications. It is designed to provide high-frequency stability in a compact form factor. --- ### 1. Key Technical Specifications The following table summarizes the primary electronic characteristics of this component series: | Parameter | Typical Specification | | :--- | :--- | | **Output Frequency** | 1.0 MHz to 125.0 MHz (Programmable) | | **Supply Voltage (Vcc)** | 1.8V, 2.5V, or 3.3V (Model dependent) | | **Frequency Stability** | ±25ppm, ±50ppm, or ±100ppm | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Output Load** | 15 pF (CMOS) | | **Current Consumption** | 10mA - 25mA (Depending on frequency) | | **Package Size** | 7.0 x 5.0 mm or 5.0 x 3.2 mm (Standard SMD) | --- ### 2. Functional Components The "F2TS-80" architecture consists of several internal electronic stages: 1. **Phase-Locked Loop (PLL) IC:** Unlike fixed crystals, the "R/Q" variants often use a PLL to multiply or divide a base reference frequency to reach the specific target output. 2. **AT-Cut Quartz Crystal:** The internal physical resonator that provides the base mechanical vibration. 3. **CMOS Output Driver:** Ensures the signal has sharp rise/fall times and is compatible with standard logic levels (High/Low). 4. **Tri-state Function (OE):** Pin 1 usually supports an "Output Enable" function, allowing the oscillator to enter a high-impedance state to save power. --- ### 3. Part Number Breakdown (Nomenclature) While coding varies by manufacturer (often Fox Electronics or similar timing specialists), the suffix usually denotes: * **R:** Refers to specific packaging (e.g., Tape & Reel). * **Q:** Often indicates **Automotive Grade** (AEC-Q200 qualification) or a specific frequency tolerance/stability tier. * **80:** Generally refers to the package size or a specific frequency series (80 MHz base or specific 7x5mm footprint). --- ### 4. Implementation Example To integrate this part into a digital circuit, a standard decoupling capacitor is required: ```c // Circuit Connectivity Guidelines: // Pin 1: OE (Output Enable) -> Connect to VCC for active output // Pin 2: GND -> System Ground // Pin 3: Output -> Connect to MCU Clock Input // Pin 4: VCC -> 0.1uF Bypass Capacitor to Ground ```
