The part number **48AV-4CVZ-R** typically refers to a high-performance **Crystal Oscillator (XO)** or a related timing component, often manufactured by companies like *Renesas (formerly IDT)* or similar specialty timing component vendors. Below is a detailed breakdown of the electronic specifications and characteristics associated with this series of components. --- ## 1. Component Overview This device is a precision frequency source used to provide a stable clock signal for digital circuits. It is commonly utilized in networking, telecommunications, and high-speed data transfer applications. ### Key Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | LVDS or LVPECL (Low-Voltage Differential Signaling) | | **Operating Voltage** | Typically 2.5V or 3.3V | | **Package Size** | Often 5.0mm x 3.2mm or 7.0mm x 5.0mm (Surface Mount) | | **Frequency Stability** | ±20ppm to ±50ppm (varies by sub-model) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ## 2. Technical Breakdown ### Differential Signaling The "4C" or "4V" designations often point to the signaling standard. Differential signaling (like LVDS) is used to: * **Reduce Noise:** It rejects common-mode interference. * **High Speed:** It allows for much higher clock frequencies than standard CMOS logic. * **Low Power:** It maintains a low voltage swing to save energy at high speeds. ### Jitter Performance These oscillators are characterized by **Ultra-Low Phase Jitter** (often < 300fs RMS). This is critical for: * Serializing/Deserializing data (SerDes). * High-speed Ethernet (10G/40G/100G). * Fiber Channel applications. --- ## 3. Pin Configuration (Typical) Most oscillators in this category follow a standard 6-pin SMT footprint: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | OE or NC | Output Enable (High = Active) or No Connect | | **2** | NC | No Internal Connection | | **3** | GND | Ground Connection | | **4** | Output | The primary clock signal | | **5** | Complementary Output | The inverted clock signal (for differential pairs) | | **6** | Vdd | Power Supply Input | --- ## 4. Implementation Example To use this part in a circuit, you would typically interface it with an FPGA or an ASIC as shown in the conceptual snippet below: ```cpp // Logic representation of a Clock Input handling an LVDS signal module ClockBuffer ( input wire clk_p, // Positive terminal from 48AV-4CVZ-R input wire clk_n, // Negative terminal from 48AV-4CVZ-R output wire system_clk ); // Differential Buffer Instantiation (e.g., IBUFGDS for Xilinx) IBUFGDS ibuf_inst ( .I(clk_p), .IB(clk_n), .O(system_clk) ); endmodule ``` ---
