The part number **O-CS8-APSYZEWU-R** appears to be a specific manufacturer configuration, often associated with high-precision **Clock Oscillators** or **Crystal Oscillators** (frequently from brands like Taitien or similar timing component specialists). Below is a breakdown of the typical electronic characteristics and specifications associated with this type of component. --- ### 1. General Specifications These components are surface-mount devices (SMD) used to provide a stable clock signal for microprocessors, FPGAs, and communication interfaces. | Feature | Typical Specification | | :--- | :--- | | **Component Type** | CMOS Output Crystal Oscillator | | **Frequency Stability** | ±25ppm to ±50ppm (Standard) | | **Supply Voltage (Vdd)** | 1.8V, 2.5V, or 3.3V (Model dependent) | | **Operating Temp Range** | -40°C to +85°C (Industrial Grade) | | **Output Load** | 15pF | | **Package Size** | 2.5 x 2.0 mm or 3.2 x 2.5 mm | --- ### 2. Key Internal Components An oscillator of this class consists of two primary electronic elements integrated into a single package: 1. **AT-Cut Quartz Crystal:** The mechanical resonating element that determines the fundamental frequency. 2. **Oscillator IC (ASIC):** * **Inverter/Amplifier:** Sustains the oscillation. * **Frequency Divider:** (Optional) If the output frequency is a sub-multiple. * **Output Buffer:** Ensures the signal is strong enough to drive the PCB trace (usually CMOS logic levels). * **Tri-state Function:** Allows the output to be disabled (High-Impedance) for power saving or testing. --- ### 3. Pin Configuration (Typical 4-Pad Layout) Most "CS8" style oscillators follow a standard industry footprint: | Pin # | Function | Description | | :--- | :--- | :--- | | **1** | OE or NC | Output Enable (High = Active, Low = High-Z) | | **2** | GND | Circuit and Package Ground | | **3** | Output | Frequency Signal Output | | **4** | Vdd | DC Power Supply Voltage | --- ### 4. Application Use Cases * **Networking:** Ethernet switches and routers requiring low jitter. * **Consumer Electronics:** Wearables and handheld devices due to the small "CS" form factor. * **Industrial:** Embedded controllers requiring stable timing over wide temperature ranges. ---
