Technical Specifications Below are the primary electronic characteristics of this component: | Feature | Specification | | :--- | :--- | | **Output Frequency** | 1.0000 MHz to 70.0000 MHz (Specific to exact sub-model) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage ($V_{CC}$)** | 5.0V DC (Typical) | | **Frequency Stability** | ±100 ppm (Standard for the -R series) | | **Operating Temp Range** | 0°C to +70°C (Commercial) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full Size | | **RoHS Status** | Compliant (Indicated by -R suffix) | --- ### 2. Internal Block Diagram & Logic The device is a self-contained timing unit that integrates the following components into a single hermetically sealed metal package: * **Quartz Crystal Resonator:** The mechanical reference for frequency. * **Oscillator IC:** Provides the gain to sustain oscillation and shapes the output waveform. * **Output Buffer:** Ensures the signal can drive the specified load (usually 15pF to 50pF) without frequency pulling. --- ### 3. Pin Configuration (14-Pin DIP Layout) Although it has a 14-pin footprint, only 4 pins are typically active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / E/D | No Connection or Output Enable/Disable | | **7** | GND | Circuit and Case Ground | | **8** | Output | Square wave clock signal output | | **14** | $V_{CC}$ | +5.0V Power Supply | --- ### 4. Key Application Areas Due to its 5V operation and stable CMOS output, it is commonly found in: 1. **Legacy Computing:** Microprocessor clocking for older systems requiring 5V logic. 2. **Industrial Controllers:** PLC (Programmable Logic Controller) timing. 3. **Networking:** Base stations and routers requiring high-reliability clock references. 4. **Test Equipment:** Signal generators and frequency counters. --- ### 5. Implementation Notes * **Bypass Capacitor:** It is highly recommended to place a **0.01µF to 0.1µF** ceramic capacitor between Pin 14 ($V_{CC}$) and Pin 7 (GND) as close to the device as possible to reduce noise. * **Termination:** If the clock trace is long, a series termination resistor (typically 22Ω to 47Ω) should be used at the output pin to prevent signal overshoot and ringing.
