LFSPXO082203

Overview

The IQD LFSPXO082203 is a surface-mount active crystal oscillator from the IQXO-791 series, designed for industrial applications. It features a standard 2.5x2.0mm ceramic package with a hermetic metal lid, providing robust protection against interference and environmental factors. The device operates at a nominal frequency of 19.2MHz with a full temperature accuracy of ±25ppm across -20°C to +70°C. It supports a supply voltage of 3.3V±10% and delivers HCMOS output signals. Key performance metrics include a typical aging rate of ±3ppm/year at 25°C, peak-to-peak period jitter of ±80ps, and phase jitter of 1psrms within the 12kHz–20MHz bandwidth.

Feature Summary

• Hermetically sealed ceramic package with metal lid for enhanced dust and moisture resistance
• HCMOS output interface compatible with direct MCU and Ethernet PHY connections
• Low power consumption with independent enable pin for standby current control

Applications

• Industrial edge gateway clocking solutions
• IoT devices requiring low-power operation
• High-speed ADC clock sources
• Gigabit Ethernet PHY interfaces

Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing this component. Confirm that the requested part matches the IQXO-791 series specifications, particularly the 2.5x2.0mm footprint and hermetic sealing requirements. Ensure compatibility with the target operating temperature range and supply voltage constraints before finalizing procurement orders.

Selection Notes

Select this oscillator for projects demanding high stability in compact form factors. The ±25ppm accuracy over the industrial temperature range suits most general-purpose timing needs. Consider the low aging rate for long-term drift management. The integrated enable function makes it suitable for battery-powered or energy-constrained systems where clock gating is required to extend operational life.
