LFSPXO083322

Overview

The LFSPXO083322 is a surface mount clock oscillator from IQD Frequency Products, designed for industrial applications. It operates at a nominal frequency of 100 MHz with a full temperature stability of ±50 ppm and an annual aging rate of ±3 ppm maximum at 25°C. The device features a standard LVDS output format, compatible with 100 Ω differential lines, and supports a supply voltage range of 2.5 V ±5%. It includes a standby control function accessible via Pin 1, allowing for low-power operation with a standby current of 10 μA. The unit utilizes a hermetically sealed ceramic package with a metal lid, ensuring robust performance in demanding environments.

Feature Summary

• Hermetically sealed ceramic package with a metal seam-welded lid for industrial-grade protection
• Standard LVDS output interface directly compatible with FPGA and high-speed ADC inputs
• Integrated standby control function enabling low-power operation with minimal current draw

Applications

• High-speed analog-to-digital converter (ADC) reference clocks
• Gigabit Ethernet and SerDes interface timing sources
• Industrial control systems requiring stable differential clock signals

Procurement Notes

Verify the specific suffix of the part number to confirm packaging details, as bulk and reel options exist within the product line. Ensure the selected variant matches the required operating temperature range for your application, noting that certain extended temperature versions are designated for industrial use only and may not be suitable for automotive safety-critical systems without separate certification. Cross-reference manufacturer datasheets for precise electrical tolerances before finalizing procurement.

Selection Notes

Select this component when a stable 100 MHz differential clock is required for high-speed data acquisition or communication interfaces. The LVDS output eliminates the need for additional level-shifting circuitry, simplifying PCB layout. Consider the hermetic sealing if environmental durability is a priority. Verify that the system power rail can support the specified voltage range and that the design accounts for the maximum startup time to ensure proper clock synchronization upon power-up.

Part Context

This oscillator belongs to the IQXO-618 series, characterized by its industrial-grade construction and reliable performance in harsh conditions. The series is engineered to provide precise timing solutions for complex electronic systems where signal integrity and long-term stability are critical. The specific model leverages advanced MEMS or crystal technology housed in a protective ceramic package to minimize external interference and mechanical stress.

Replacement Considerations

Direct substitutes include other industrial-grade 100 MHz LVDS oscillators with similar pinouts and hermetic packaging. When replacing, verify that the alternative component meets the same ±50 ppm stability requirement and LVDS electrical specifications to maintain system compatibility.
