The **K1528DBE-R** is a specialized electronic component, typically categorized as a **Surface Mount Device (SMD)**, specifically a high-precision **Voltage Controlled Crystal Oscillator (VCXO)** or a related timing module. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The part number follows the standard naming conventions used by manufacturers like **Kyocera/AVX** or similar precision frequency control providers. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Voltage Controlled Crystal Oscillator (VCXO) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Frequency Stability** | ±20ppm to ±50ppm (varies by grade) | | **Output Type** | CMOS / LVPECL (Application dependent) | | **Operating Voltage** | 3.3V or 5.0V DC | | **Package Size** | Compact (e.g., 7.0 x 5.0 mm or 5.0 x 3.2 mm) | --- ### 2. Key Internal Components To understand the "electronic parts" of the K1528DBE-R, we must look at its internal architecture: * **Quartz Crystal Resonator:** The heart of the device, providing the base stable frequency. * **Varactor Diode:** Used for frequency tuning. By applying a control voltage, the capacitance changes, slightly shifting the crystal's resonant frequency. * **Oscillator IC:** An integrated circuit that maintains the oscillation and provides the buffer for the output signal. * **Bypass Capacitors:** Internal surface-mount capacitors used to filter noise from the power supply. --- ### 3. Pinout Configuration A typical K1528 series component utilizes a 4-pin or 6-pin configuration: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | **V_control** | Voltage input to adjust the output frequency. | | **2** | **OE / NC** | Output Enable (high/low logic) or No Connection. | | **3** | **GND** | Circuit Ground. | | **4** | **Output** | The generated clock signal (Square wave). | | **5** | **NC** | No internal connection (on 6-pin models). | | **6** | **Vcc** | Power Supply Voltage. | --- ### 4. Common Applications Due to its precision and the ability to "tune" the frequency, this part is found in: 1. **Phase-Locked Loops (PLLs):** For synchronizing signals. 2. **Telecommunications:** Base stations and networking hardware. 3. **Digital Video:** Used in broadcasting equipment to sync frames. 4. **Frequency Synthesizers:** Generating stable high-frequency signals from a lower reference. --- ### 5. Part Number Decoding (Typical) * **K1528:** Series identifier (VCXO Architecture). * **D:** Usually denotes the Supply Voltage (e.g., 3.3V). * **B:** Often represents the Frequency Stability grade. * **E:** Operating Temperature range (e.g., -40°C to +85°C). * **R:** Packaging code (Tape & Reel).
