### K1110BAC-R: Overview and Technical Specifications The **K1110BAC-R** is a specific model of a **Crystal Clock Oscillator**, typically manufactured by companies like **Microchip (formerly Vectron/CTS)** or similar high-precision timing component providers. It belongs to the K1100 series, which are industry-standard, high-reliability oscillators used to provide a stable frequency for digital circuits. --- ### 1. Key Technical Specifications Below are the typical electronic characteristics for the K1110BAC-R: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | Full-size / Half-size DIP package | | **Frequency Range** | Usually 1.0 MHz to 100 MHz | (Specific value depends on variant) | | **Supply Voltage (Vcc)** | +5.0V DC (±10%) | Standard TTL/CMOS voltage | | **Output Type** | TTL / CMOS Compatible | Capable of driving multiple loads | | **Package Style** | 14-pin DIP (4 pins used) | Metal hermetic seal | | **Operating Temp** | 0°C to +70°C | Commercial grade | | **Frequency Stability** | ±100 ppm | Standard stability over temperature | --- ### 2. Pin Configuration Although the device is shaped like a 14-pin Integrated Circuit (DIP), only four pins are electrically functional. | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | N/C or Tri-state | No connection or Output Enable/Disable | | **Pin 7** | GND | Circuit Ground / Case Ground | | **Pin 8** | Output | The generated clock signal (Square Wave) | | **Pin 14** | Vcc | Power Supply (+5V) | --- ### 3. Core Electronic Components Inside the metal housing (can), the K1110BAC-R consists of several critical parts: * **Quartz Crystal Resonator:** The "heart" of the component, providing the fundamental physical vibration. * **Oscillator Integrated Circuit (IC):** An internal amplifier and feedback loop that maintains the crystal's vibration. * **Bypass Capacitors:** Internal surface-mount capacitors to reduce power supply noise. * **Hermetic Metal Package:** The outer shell is filled with nitrogen and sealed to prevent moisture from affecting the frequency. --- ### 4. Circuit Implementation To use this part in a circuit, follow this basic schematic logic: ```c // Connection Logic: 1. Connect Pin 7 to System Ground (GND). 2. Connect Pin 14 to +5.0V. 3. Place a 0.01uF to 0.1uF decoupling capacitor near Pin 14. 4. Take the clock signal from Pin 8 to your MCU/FPGA/Logic gate. ``` --- ### 5. Common Applications * **Microprocessor Clocks:** Providing the master heartbeat for CPUs. * **Networking Gear:** Timing for Ethernet or data transmission. * **Industrial Controllers:** Reliable clocking for PLCs and embedded systems. * **Legacy Hardware:** Often found in vintage computing equipment due to the 14-pin DIP form factor.
