The **K1100BACE-R** is a specific electronic component, primarily recognized as a **Crystal Clock Oscillator**. It is manufactured by Microchip (formerly under the Microsemi/Vectron branding) and is widely used in timing circuits to provide a stable frequency reference. --- ## 1. Technical Specifications Below are the key electronic parameters for the K1100BACE-R: | Feature | Specification | | :--- | :--- | | **Component Type** | Quartz Crystal Clock Oscillator | | **Package / Case** | 14-Pin DIP (Full Size) | | **Output Frequency** | Usually ranges (check specific batch, often 1.0 MHz to 100 MHz) | | **Supply Voltage (Vcc)** | +5.0 VDC (±10%) | | **Output Logic** | TTL (Transistor-Transistor Logic) | | **Operating Temperature** | 0°C to +70°C (Commercial Grade) | | **Frequency Stability** | ±100 ppm (Standard) | | **RoHS Compliant** | Yes (Indicated by the "-R" suffix) | --- ## 2. Pin Configuration (14-Pin DIP) Although it uses a 14-pin footprint, most pins are "No Connect" (NC) or used for structural support. Only four pins are active: * **Pin 1:** NC (No Connection) or Tri-state Control (depending on specific sub-version). * **Pin 7:** Case Ground (GND). * **Pin 8:** Output (Frequency signal). * **Pin 14:** Supply Voltage (+5V Vcc). --- ## 3. Key Electronic Characteristics ### A. TTL Compatibility The "BAC" designation in the part number often refers to its compatibility with TTL logic levels. This means it can directly drive other TTL integrated circuits (ICs) without needing level shifters, provided they operate at 5V. ### B. "R" Suffix Significance The **-R** at the end of the part number denotes **RoHS Compliance**. This indicates that the component is manufactured without hazardous substances like lead, making it suitable for modern environmental standards and international shipping. ### C. Hermetic Sealing The unit is housed in a metal "Can" package. This provides: 1. **EMI Shielding:** Reduces electromagnetic interference to and from the oscillator. 2. **Environmental Protection:** Protects the internal quartz crystal from moisture and atmospheric pressure changes. --- ## 4. Typical Applications * **Microprocessor Clocks:** Providing the "heartbeat" for older 8-bit or 16-bit CPUs. * **Industrial Controllers:** Used in PLCs or timing modules where a robust 14-pin DIP through-hole component is preferred for durability. * **Legacy Hardware Repair:** Frequently found in vintage computing and telecommunications equipment from the 1990s and early 2000s. ---
