Based on the part number **W2AP-G35-R/CE**, this component is a high-performance **Crystal Oscillator** (specifically a Temperature Compensated Crystal Oscillator or TCXO variant) often used in precision timing applications. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. Component Overview The "W2AP" series typically refers to miniature surface-mount device (SMD) oscillators designed for stable frequency output despite environmental changes. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (SMD) | | **Package Size** | 2.5mm x 2.0mm (Standard 2520) | | **Output Type** | CMOS / Clipped Sine Wave | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Standard Frequency** | Commonly 26MHz, 38.4MHz, or 52MHz (Varies by sub-spec) | --- ### 2. Technical Specifications The suffix codes provide specific data regarding the electrical behavior of the part: * **G35:** Generally refers to the stability and temperature range. This often implies a frequency stability of ±0.5ppm to ±2.0ppm over a wide temperature range (e.g., -40°C to +85°C). * **R:** Indicates "Tape and Reel" packaging for automated pick-and-place assembly. * **CE:** Compliance marking, often signifying **Conformité Européenne** (European Conformity) or specific low-power CMOS electrical characteristics. --- ### 3. Key Electronic Characteristics #### A. Power Supply (Vcc) These parts typically operate at low voltages to accommodate modern mobile chipsets: * **Operating Voltage:** Usually 1.8V, 2.8V, or 3.3V. * **Current Consumption:** Very low (typically < 2.0mA), making it ideal for battery-operated devices. #### B. Frequency Stability Because this part is often used in RF (Radio Frequency) circuits, it maintains a very tight "tolerance." It corrects for frequency "drift" that occurs when the device heats up or cools down. #### C. Phase Noise Designed with low phase noise to ensure clean signal processing in communication modules (like GPS, Wi-Fi, or LTE). --- ### 4. Common Applications Due to its small footprint and high stability, the **W2AP-G35-R/CE** is found in: 1. **Smartphones:** Providing the reference clock for RF transceivers. 2. **GPS/GNSS Modules:** Requiring high precision for satellite synchronization. 3. **IoT Devices:** Where space is limited but timing accuracy is critical. 4. **Wearables:** Such as smartwatches that require low power consumption. ---
