The **K1100BACS-R** is a specific electronic component primarily identified as a **Crystal Oscillator**. These parts are essential in electronic circuits for generating stable clock signals. --- ## 1. Component Overview The K1100 series, often manufactured by companies like **Microchip (formerly Microsemi/Vectron)** or **Kyocera**, is a legacy line of quartz crystal oscillators. The "R" suffix typically denotes **RoHS compliance** (Lead-free). ### Key Specifications | Feature | Typical Specification | | :--- | :--- | | **Package Type** | 14-Pin DIP (Full Size) | | **Technology** | Quartz Crystal (XO) | | **Output Type** | TTL / CMOS Compatible | | **Voltage Supply** | Usually 5.0V DC | | **Frequency Range** | Fixed (Varies by specific sub-model) | | **Standard Stability** | ±100 ppm or ±50 ppm | --- ## 2. Pin Configuration Although it uses a 14-pin DIP footprint, only four pins are physically connected to the internal circuitry: | 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** | Vcc | Positive Power Supply (+5V) | --- ## 3. Circuit Application In an electronic system, the K1100BACS-R acts as the "heartbeat." It provides a steady pulse that synchronizes the operations of other components. * **Microprocessors:** Providing the base clock for CPU cycles. * **Networking:** Timing for data transmission in Ethernet or Serial interfaces. * **Legacy Systems:** Commonly found in older industrial controllers and 80s/90s computing hardware due to its robust DIP package. --- ## 4. Technical Characteristics * **Hermetic Sealing:** The metal "can" package is hermetically sealed to protect the quartz crystal from moisture and atmospheric changes, ensuring long-term frequency stability. * **Waveform:** It produces a **Square Wave** output, which is standard for digital logic circuits. * **Through-Hole Mounting:** Designed for traditional PCB soldering or insertion into IC sockets.
