LFSPXO082156

Overview

The LFSPXO082156 is a 32.768 MHz standard CMOS oscillator from the IQXC-540 series, manufactured by IQD Frequency Products. It operates on a single 3.3V supply with a tolerance of ±10%. The device features a frequency stability of ±25 ppm over the operating temperature range and an annual aging rate of ±5 ppm. It utilizes a compact 2.0 x 1.6 mm ceramic package with a hermetically sealed metal lid. Key electrical parameters include a maximum operating current of 7 mA and a standby current of 10 µA when disabled.

Feature Summary

• Hermetically sealed construction using a ceramic package and metal seam-welded lid for environmental protection
• Integrated power-down functionality allowing low-power standby mode via logic control
• Compact surface-mount design suitable for space-constrained industrial applications

Applications

• Industrial edge gateways requiring low-power clock sources
• Battery-powered consumer electronics needing extended standby life
• BLE communication modules utilizing 32.768 MHz reference frequencies

Procurement Notes

Verify the specific ordering suffix to confirm the exact frequency stability grade and packaging format. Ensure the enable pin voltage thresholds align with the system's logic levels for proper power-down operation. Confirm that the hermetic seal requirements match the environmental specifications of the target application before finalizing procurement.

Selection Notes

Select this component when a small footprint is required alongside moderate frequency stability. The integrated standby feature makes it suitable for battery-operated devices where reducing quiescent current during sleep modes is critical. Consider the ±25 ppm stability sufficient for general timing applications rather than high-precision measurement systems.

Part Context

This part belongs to the IQXC-540 series of surface-mount oscillators. It is designed as a drop-in replacement for larger packages while maintaining hermetic sealing capabilities. The series targets applications balancing size constraints with reliability requirements in industrial and consumer sectors.

Replacement Considerations

The Wurth Elektronik part number 830208215609 is documented as a corresponding alternative with identical core specifications.

FAQ

How is the power-down mode activated?

The output is disabled and the device enters high-impedance standby mode when Pin 1 is pulled to a voltage level less than or equal to 30% of VCC.

What is the default state if the enable pin is left floating?

If Pin 1 is left unconnected (floating), the oscillator defaults to having its output enabled.
