LFSPXO082149

Overview

The LFSPXO082149 is a standard clock oscillator from the IQXO-540 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 12.288 MHz and utilizes a compact 2.0 x 1.6 mm ceramic package with a hermetically sealed metal lid. The device supports a supply voltage range of 2.97 V to 3.63 V and delivers an HCMOS output signal. It features a total frequency stability of ±25 ppm across the industrial temperature range of -20°C to +70°C. The oscillator draws a maximum operating current of 4 mA and a standby current of up to 10 μA when disabled.

Procurement Notes

Verify the specific suffix against the official datasheet to confirm exact frequency tolerance and temperature range specifications. Ensure the ordering part number matches the required package dimensions and output drive capabilities. Confirm RoHS compliance status and lead times directly with authorized distributors or IQD Frequency Products before finalizing procurement plans.

Selection Notes

Select this component when a small footprint is critical alongside high frequency accuracy for audio applications. The 12.288 MHz frequency is optimal for 48 kHz sampling systems. Consider the low standby current for battery life extension. Verify that the load capacitance requirements of the destination circuit align with the oscillator's specified drive level.

Part Context

This model belongs to the IQXO-540 series of surface-mount oscillators. The series is characterized by its miniature ceramic packaging and robust performance metrics.
