Based on the part number **QVC451663RT-7035**, this component belongs to a specialized category of radio frequency (RF) hardware, specifically a **Voltage Controlled Crystal Oscillator (VCXO)** or a **Dielectric Resonator Oscillator (DRO)** module, often manufactured by companies like Murata or specialized RF component suppliers. Below is a detailed breakdown of the electronic characteristics and specifications typical for this series. --- ### 1. General Specifications These modules are designed for high-stability frequency generation in telecommunications equipment, such as base stations and microwave links. | Feature | Description | | :--- | :--- | | **Component Type** | RF Oscillator / VCXO | | **Technology** | Quartz Crystal or Dielectric Resonator | | **Primary Function** | Frequency synthesis and timing | | **Application** | Cellular Infrastructure (GSM/WCDMA/LTE), Point-to-point radio | | **Mounting Type** | Surface Mount (SMD) | --- ### 2. Technical Parameters The suffix **-7035** often refers to specific frequency tuning or the physical dimensions (7.0mm x 3.5mm or 7.0mm x 5.0mm footprint). #### Electrical Characteristics * **Operating Voltage:** Typically ranges from **3.3V to 5.0V DC**. * **Control Voltage ($V_c$):** Used to "pull" or adjust the frequency. Usually between **0.5V and 2.5V**. * **Frequency Range:** High MHz to Low GHz range (depending on the specific sub-series configuration). * **Stability:** High thermal stability, often rated in parts per million (ppm). --- ### 3. Pinout Configuration (Generic) Most parts in this series utilize a standard 4 or 6-pad SMD layout: 1. **VC (Voltage Control):** Input to adjust the output frequency. 2. **GND:** Ground connection. 3. **OUT:** RF output signal. 4. **Vcc:** DC power supply input. 5. *(Optional)* **OE:** Output Enable (logic high/low). --- ### 4. Key Advantages * **Low Phase Noise:** Critical for maintaining signal integrity in high-speed data transmission. * **Compact Form Factor:** Designed for dense PCB layouts in modern networking hardware. * **Environmental Resilience:** Often built to industrial temperature grades (-40°C to +85°C). --- ### 5. Identification Code Breakdown While proprietary, the nomenclature usually follows this logic: * **QVC:** Product Series (Quartz/Voltage Controlled). * **451663:** Internal design/frequency identifier. * **RT:** RoHS compliant / Tape & Reel packaging. * **7035:** Case size or center frequency modifier. ---
