LFSPXO082220

Overview

The IQD Frequency Products LFSPXO082220 is a surface-mount standard clock oscillator from the IQXO-794 series. It operates at a nominal frequency of 12.288 MHz with a supply voltage of 1.8V. The device features HCMOS output format and is housed in a compact 2.5 mm x 2.0 mm ceramic package with a hermetic metal lid. It provides a frequency stability of ±25 ppm over an operating temperature range of -20°C to +70°C, with a maximum annual aging rate of ±3 ppm.

Feature Summary

• Hermetically sealed ceramic construction with a metal lid for environmental protection
• Integrated enable/disable control function via Pin 1 for power management
• HCMOS output compatible with 1.8V logic levels without external level shifting
• Compact 2.5x2.0mm footprint optimized for space-constrained portable designs

Applications

• Audio equipment requiring 256x oversampling for 48kHz sampling rates
• Portable consumer devices with strict board area limitations
• Microcontroller systems operating at 1.8V I/O levels
• ADC clock sources in low-power embedded applications

Procurement Notes

Verify the specific suffix of the part number to confirm packaging type, as bulk and reel options exist within the LFSPXO series. Ensure the design supports the 1.8V supply requirement and utilizes the enable pin correctly, either floating or pulled high, to avoid default shutdown states. Confirm that the 2.5x2.0mm package dimensions fit the target PCB layout constraints.

Selection Notes

Select this component when a 12.288MHz clock is required for audio processing or precise timing without PLL complexity. It is suitable for designs where 1.8V operation eliminates the need for level shifters. Choose this model over larger packages like 3225 when board real estate is critical. Ensure the application environment stays within the -20°C to +70°C range for specified stability.
