The **XLL32V** is a high-performance, ultra-low jitter crystal oscillator (XO) belonging to Renesas' (formerly IDT) XL series. These components are specifically designed for applications requiring high precision and reliability in data transmission. --- ### ## Technical Specifications Overview The XLL32V operates using **LVDS (Low Voltage Differential Signaling)** logic, which is favored in high-speed circuits for its low power consumption and high noise immunity. | Parameter | Specification | | :--- | :--- | | **Output Type** | LVDS | | **Supply Voltage (Vdd)** | 2.5V | | **Frequency Range** | 0.750 MHz to 1350 MHz | | **Phase Jitter (12kHz - 20MHz)** | < 1 ps RMS (typical 0.6 ps) | | **Package Size** | 3.2 x 2.5 mm (Small Form Factor) | | **Operating Temperature** | -40°C to +85°C (Standard Industrial) | --- ### ### Key Electronic Characteristics 1. **Low Phase Jitter:** The primary electronic advantage of the XLL32V is its extremely low jitter. In high-speed networking (like 10G/40G/100G Ethernet), jitter can cause data bit errors. The XLL32V ensures a clean clock signal. 2. **Differential Output:** Because it uses LVDS, it outputs two signals that are inverses of each other. This allows the receiver to reject common-mode noise, making it ideal for crowded PCBs with significant electromagnetic interference (EMI). 3. **Frequency Stability:** It utilizes a quartz crystal resonator combined with a proprietary ASIC to maintain stable frequency outputs across varying temperatures and voltages. 4. **Tri-State Function (Output Enable):** Pin 1 usually acts as an "Enable/Disable" control. When disabled, the output goes into a high-impedance state, reducing power consumption when the clock signal is not needed. --- ### ### Typical Applications * **Networking:** Ethernet switches, routers, and line cards. * **Storage:** Fiber Channel, SATA, and SAS interfaces. * **Communications:** Wireless base stations and optical modules. * **Computing:** High-speed I/O and FPGA clocking. --- ### ### Pin Configuration (3.2 x 2.5 mm Package) ```text Pin 1: OE (Output Enable) Pin 2: No Connect (or NC) Pin 3: GND (Ground) Pin 4: Output (Positive) Pin 5: Complementary Output (Negative) Pin 6: Vdd (Power Supply) ```
