## Overview of the K1525CAM-R The **K1525CAM-R** is a high-precision, high-stability **TCXO (Temperature Compensated Crystal Oscillator)** typically manufactured by CTS Corporation (formerly Champion Technologies). It is designed for applications requiring extremely stable frequency outputs in environments where temperature fluctuations would normally affect a standard crystal. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Package Type** | 14-pin DIP (Dual In-line Package) Compatible | | **Output Type** | CMOS / HCMOS | | **Standard Frequency** | Varies (Commonly used in 10MHz, 20MHz, etc.) | | **Supply Voltage ($V_{cc}$)** | +5.0 VDC (Standard) | | **Operating Temperature** | -30°C to +75°C (Standard Industrial) | | **Stability vs Temperature** | ±1.0 ppm to ±2.5 ppm | --- ### Key Electronic Components & Features The device functions as a self-contained timing system. Internally, it consists of several key stages: 1. **Quartz Crystal Resonator:** The heart of the part, providing the base frequency. 2. **Compensation Network:** A specialized circuit (often using varactor diodes and thermistors) that adjusts the capacitance of the crystal circuit based on sensed temperature to counteract frequency drift. 3. **Buffer Amplifier:** Ensures the output signal is strong enough to drive downstream digital logic (CMOS/HCMOS levels) without distorting the frequency. 4. **Voltage Regulator:** Internal regulation to minimize frequency shifts caused by variations in the input supply voltage. --- ### Pin Configuration (Typical 14-Pin DIP Layout) Though it sits in a 14-pin footprint, only a few pins are active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | V.C. / N.C. | Voltage Control (if VCTCXO) or No Connection | | **7** | GND | Case and Circuit Ground | | **8** | Output | The frequency signal (CMOS/HCMOS) | | **14** | $V_{cc}$ | +5.0V Power Supply Input | --- ### Applications * **Telecommunications:** Base stations and wireless infrastructure. * **Networking:** Synchronous Ethernet and SONET/SDH timing. * **Test & Measurement:** Frequency counters and signal generators. * **GPS/Navigation:** Stable clocking for position calculation. ---
