LFSPXO076043

Overview

The LFSPXO076043 is a standard crystal oscillator from the IQXO-691 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of ±50 ppm. The device utilizes a CMOS output format and requires a supply voltage of 0.9 V. It features an enable/disable function, drawing a maximum supply current of 10 mA during operation and 100 µA when disabled. The component is housed in a compact 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a maximum height of 1.00 mm. It is designed for surface-mount installation and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates an enable/disable control function for power management
• Utilizes a low-profile surface-mount ceramic package
• Provides stable CMOS clock signals at 40 MHz

Applications

• Portable electronic devices requiring low-power clock sources
• Embedded systems with strict size constraints
• Battery-operated equipment needing efficient power usage

Procurement Notes

Verify the specific packaging configuration required for production, as this part number may be associated with reel or tape-and-reel formats depending on distributor inventory. Confirm that the 0.9V supply voltage aligns with the target system's logic levels. Ensure the enable/disable pin functionality is correctly integrated into the circuit design to utilize the low standby current feature effectively.

Selection Notes

Select this component when a small footprint and low supply voltage are critical requirements. The 2.5mm x 2mm package suits dense PCB layouts. Consider the ±50 ppm stability sufficient for general timing applications. The enable/disable capability offers flexibility for power-sensitive designs compared to continuously running oscillators.

Part Context

This oscillator belongs to the IQXO-691 series, which focuses on miniaturized, low-power solutions. It complements other IQD products like the LFXTAL030043 crystal and LFSPXO076039 oscillator by offering a standardized, ready-to-use clock signal in a comparable small form factor, simplifying design-in processes for manufacturers.

Replacement Considerations

Direct replacements must match the 40 MHz frequency, 0.9V supply, CMOS output, and 2.5x2mm package dimensions. Verify compatibility of the enable/disable logic polarity if substituting with similar models from other manufacturers.
