The **K1525CAMB-R** is a specific electronic component within the category of **Quartz Crystal Oscillators**. These parts are primarily used to provide a precise and stable clock signal for digital circuits. --- ## Technical Specifications Below are the typical technical parameters for the K1525 series, which is a common part number used by manufacturers like **Champion Technologies** (now part of other entities). | Feature | Specification | | :--- | :--- | | **Component Type** | Quartz Crystal Clock Oscillator (XO) | | **Package Style** | Through-Hole (14-pin DIP compatible) | | **Supply Voltage ($V_{cc}$)** | +5.0V DC | | **Output Type** | CMOS / TTL | | **Frequency Stability** | $\pm$100 ppm (standard for this series) | | **Operating Temperature** | 0°C to 70°C (Commercial grade) | | **RoHS Compliance** | Yes ("-R" suffix indicates RoHS compliant) | --- ## Pin Configuration While it sits in a 14-pin DIP footprint, it usually only utilizes four pins: 1. **Pin 1 (NC/Enable):** No Connection or Output Enable/Disable. 2. **Pin 7 (GND):** Ground connection. 3. **Pin 8 (Output):** The generated clock frequency signal. 4. **Pin 14 ($V_{cc}$):** +5V Power Supply. --- ## Key Features & Applications ### Key Features * **Hermetically Sealed:** The metal "can" package protects the internal quartz crystal from environmental humidity and interference. * **Integrated Circuitry:** Unlike a simple crystal, this "oscillator" includes the internal capacitors and transistors needed to start and maintain oscillation. * **Low Jitter:** Designed for timing-critical applications. ### Common Applications * **Microprocessors:** Providing the base clock for CPUs. * **Networking:** Timing for Ethernet controllers or routers. * **Legacy Hardware:** Commonly found in industrial controllers and older PC motherboards requiring a 5V logic level. --- ## Comparison: Crystal vs. Oscillator It is important to distinguish this part from a basic 2-pin crystal: ```cpp // Logic flow of the K1525CAMB-R Power (+5V) --> Internal Amplifier --> Quartz Resonator --> Square Wave Output ``` * **Crystal (XTAL):** Passive, requires external capacitors and an inverter circuit. * **K1525CAMB-R (Oscillator):** Active, only requires power to start outputting a signal.
