### K1525CDB-R Electronic Component Overview The **K1525CDB-R** is a specific type of **Crystal Oscillator** (XO), typically manufactured by companies like CTS Electronic Components. It belongs to the K1525 series, which is characterized by its DIP (Dual In-line Package) form factor and high-reliability performance. --- ### Technical Specifications The following table outlines the typical electrical and mechanical characteristics of the K1525CDB-R: | Feature | Specification | | :--- | :--- | | **Component Type** | Clock Oscillator | | **Package Type** | 14-pin DIP (Standard Full Size) | | **Output Type** | HCMOS / TTL | | **Supply Voltage ($V_{CC}$)** | 5.0V DC | | **Frequency Stability** | ±25 ppm (typical for "C" grade) | | **Operating Temperature** | 0°C to +70°C (Standard Commercial) | | **Mounting Type** | Through-Hole | --- ### Key Internal Parts and Functionality The K1525CDB-R is not a single component but an integrated module consisting of several parts inside its metal housing: 1. **Quartz Crystal Blank:** The heart of the device. It provides the precise mechanical vibration required to generate a stable frequency. 2. **Oscillator IC:** An internal integrated circuit that amplifies the signals from the crystal and converts them into a square wave (HCMOS/TTL compatible). 3. **Bypass Capacitors:** Internal surface-mount capacitors used to filter noise from the $V_{CC}$ line, ensuring frequency stability. 4. **Metal Hermetic Header:** The outer casing (usually nickel-plated) that protects the internal sensitive components from moisture and electromagnetic interference (EMI). --- ### Pin Configuration (14-Pin DIP Layout) Although it has a 14-pin footprint, most oscillators of this type only utilize four active pins: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or E/D | No Connection or Output Enable/Disable | | **7** | GND | Case and Circuit Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | $V_{CC}$ | +5.0V Power Supply | --- ### Application Use Cases * **Legacy Computing:** Providing master clock signals for older CPU architectures. * **Industrial Control:** Used in PLC (Programmable Logic Controller) boards where through-hole components are preferred for vibration resistance. * **Networking:** Timing for older Ethernet or serial communication equipment.
