LFSPXO018032

Overview

The LFSPXO018032 is a 20 MHz standard crystal clock oscillator manufactured by IQD Frequency Products. It operates on a single 5 V supply with a maximum current consumption of 20 mA. The device features an HCMOS/TTL compatible output format and supports a load capacitance of 15 pF, with a maximum drive capability of 50 pF. Total stability across the commercial temperature range (0°C to +70°C) is specified at ±50 ppm. The unit utilizes a 4-SMD surface mount package measuring 7 mm x 5 mm.

Feature Summary

• Integrated enable/disable functionality allows for low-power standby operation via pin control.
• Hermetic metal seal construction provides superior environmental protection against moisture compared to plastic packages.
• Direct compatibility with standard microcontroller and Ethernet PHY clock inputs without additional buffering.

Applications

• Industrial data acquisition board reference clocks
• Modbus communication interface timing sources
• ADC sampling systems requiring stable frequency references

Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as bulk and reel options exist within the product family. Ensure the selected variant matches the required operating temperature range and that the enable pin logic aligns with the system's power management strategy. Confirm RoHS compliance status for the specific batch prior to integration into regulated equipment designs.

Selection Notes

Select this component when a hermetically sealed oscillator is required for long-term industrial reliability. The 5V supply voltage simplifies power distribution in legacy or mixed-voltage systems. The enable feature eliminates the need for external clock gating switches, reducing bill-of-materials complexity. Verify that the ±50 ppm stability meets the total system timing budget requirements.

Part Context

This part belongs to the LFSPXO series of standard crystal oscillators from IQD Frequency Products, now part of the Würth Elektronik group. The series offers various frequencies and package sizes, with the LFSPXO018032 representing a 20 MHz option in the compact 7x5mm form factor designed for general-purpose digital timing applications.

Replacement Considerations

Cross-reference with other 20MHz HCMOS oscillators in the 7x5mm package. Verify pinout compatibility, specifically the location of the Enable/Disable control pin, before substituting with alternative manufacturers' components.

FAQ

How does the enable pin affect power consumption?

When the enable pin is driven low, the output enters a high-impedance state, reducing current consumption to approximately 10 µA.

What is the maximum load capacitance supported?

The oscillator supports a maximum load capacitance of 50 pF, though it is typically configured for a 15 pF load.
