The **K1150BAC-R** is a specific electronic component belonging to the **Crystal Oscillator** family, typically manufactured by companies like Microchip (formerly Vectron/Vectron International). It is designed to provide a precise clock signal for electronic circuits. --- ## 1. Component Classification | Category | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Technology** | CMOS/TTL Compatible | | **Package Style** | 14-pin DIP (Dual In-line Package) - Half Size | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ## 2. Technical Specifications The K1150 series is known for its stability in telecommunications and computing environments. * **Frequency Range:** Usually available between 1.000 MHz and 70.000 MHz (exact frequency is specified upon ordering). * **Supply Voltage ($V_{cc}$):** Typically **5.0V DC** (Standard for the K1150 series). * **Operating Temperature:** Generally ranges from **0°C to +70°C** (Commercial grade). * **Frequency Stability:** Often rated at **±50ppm or ±100ppm**, ensuring the clock remains accurate despite temperature fluctuations. * **Output Load:** Designed to drive up to 10 TTL loads or 15pF CMOS loads. --- ## 3. Pin Configuration (Half-Size DIP) Although it has a 14-pin footprint, most "half-size" oscillators only utilize four active pins: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / Tri-state | No Connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | $V_{cc}$ | Power Supply (+5V) | --- ## 4. Key Features & Applications ### Features * **Hermetically Sealed:** The metal "can" package protects the quartz crystal from humidity and atmospheric contaminants. * **Low Phase Jitter:** Crucial for high-speed data transmission. * **Retrofit Friendly:** The 14-pin DIP footprint is a legacy standard, making it easy to use in older industrial equipment or through-hole PCB designs. ### Common Applications 1. **Microprocessor Clocks:** Providing the heartbeat for CPUs and MCUs. 2. **Network Hardware:** Used in hubs, routers, and switches. 3. **Test & Measurement:** Found in oscilloscopes and signal generators. 4. **Legacy Systems:** Industrial controllers that require 5V logic levels. ---
