The part number **O-CS8-AMTYZEWP-R** refers to a high-precision **Oven Controlled Crystal Oscillator (OCXO)** manufactured by **Taitien**. OCXOs are specialized oscillators that use a temperature-controlled enclosure (an "oven") to maintain a constant temperature for the quartz crystal, ensuring extremely high frequency stability regardless of external environmental changes. --- ## 1. Technical Specifications Below are the typical technical parameters associated with this specific series and configuration: | Parameter | Specification Details | | :--- | :--- | | **Component Type** | Oven Controlled Crystal Oscillator (OCXO) | | **Frequency Stability** | Typically in the range of ±5 ppb to ±50 ppb | | **Package Type** | Surface Mount Device (SMD) | | **Output Type** | CMOS / Sinewave (Model dependent) | | **Supply Voltage** | 3.3V or 5.0V DC | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Aging Rate** | Very low (long-term stability) | --- ## 2. Key Features * **Thermal Management:** Internal heating circuitry keeps the crystal at its "turnover point" (the temperature where frequency change is minimal). * **Low Phase Noise:** Designed to minimize jitter, making it ideal for high-speed data transmission. * **SC-Cut Crystal:** Usually employs an SC-cut (Stress Compensated) quartz crystal which offers superior thermal stability and aging characteristics compared to standard AT-cut crystals. * **RoHS Compliant:** The "-R" suffix typically denotes compliance with RoHS (Restriction of Hazardous Substances) standards. --- ## 3. Applications This component is designed for infrastructure-level hardware where timing precision is critical: 1. **Telecommunications:** Base stations (4G/5G), Small Cells, and SyncE (Synchronous Ethernet). 2. **Network Hardware:** Stratum 3/3E clocking for switches and routers. 3. **Test & Measurement:** Frequency synthesizers and high-end lab equipment. 4. **Satellite Communications:** Earth stations and GPS disciplined clocks. --- ## 4. Deciphering the Part Number Logic While Taitien’s naming convention is proprietary, it generally breaks down as follows: * **O-CS8:** Identifies the product series (OCXO, 9.7 x 7.5 mm or similar small form factor). * **AMTY:** Internal codes for frequency, stability, and voltage requirements. * **ZEWP:** Specific custom tuning, output wave shape, or pull-range characteristics. * **-R:** RoHS compliance and Tape & Reel packaging.
