LFSPXO019992

Overview

The LFSPXO019992 is a standard clock oscillator from the CFPS-73 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a frequency stability of ±50 ppm. The device utilizes an HCMOS output format and requires a supply voltage ranging from 2.97 V to 3.63 V, with a typical value of 3.3 V. Maximum supply current is 12 mA. The component features enable/disable functionality and is housed in a 4-SMD, no-lead package measuring 7.2 mm x 5.2 mm x 1.4 mm. It supports a load capacitance of 50 pF and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• HCMOS output format for digital signal compatibility
• Integrated enable and disable control functionality
• Surface-mount design with leadless SMD packaging

Applications

• General purpose clock generation in electronic systems
• Data communication interface timing
• Microcontroller system clocks

Procurement Notes

Verify the specific ordering suffix to confirm the required packaging type, such as cut tape or reel, as these affect handling procedures. Ensure the selected variant matches the necessary frequency tolerance and temperature range specifications for the target application environment. Cross-reference the manufacturer part number with distributor codes to avoid procurement errors during sourcing.

Selection Notes

Select this component when a stable 20 MHz reference is required with HCMOS logic levels. Consider the ±50 ppm stability requirement against system jitter budgets. Verify that the 3.3 V supply rail aligns with the target circuit design. The compact 4-SMD footprint is suitable for space-constrained PCB layouts requiring surface-mount assembly processes.

Part Context

This oscillator belongs to the CFPS-73 series, which provides standard clock signals in compact surface-mount packages. The series offers various frequencies and stability options tailored for general electronics applications. The LFSPXO019992 specifically addresses needs for reliable timing references in consumer and industrial devices requiring moderate stability.

Replacement Considerations

Direct substitutes must match the 20 MHz frequency, HCMOS output, 3.3 V supply, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics before integration. Check manufacturer documentation for any pin-to-pin compatible alternatives within the same product family.
