LFSPXO025876

Overview

The LFSPXO025876 is a standard clock oscillator from the IQD Frequency Products series, operating at a nominal frequency of 13.56 MHz. It features an HCMOS/TTL output format and requires a supply voltage ranging from 4.5 V to 5.5 V. The device exhibits a frequency stability of 100 ppm and is housed in a compact 4-SMD, no-lead package. It supports a power-down mode for standby applications.

Feature Summary

• Provides stable 13.56 MHz timing signals via HCMOS/TTL compatible outputs
• Incorporates a power-down feature to enable low-power standby operation
• Utilizes a surface-mount package suitable for automated assembly processes

Applications

• Radio-frequency identification (RFID) systems requiring 13.56 MHz carriers
• Contactless smart card readers and writers
• NFC-enabled consumer electronic devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required packaging formats such as cut tape or reel. Confirm that the supply voltage range aligns with the target system design before finalizing procurement orders.

Selection Notes

Select this component when a precise 13.56 MHz reference is needed for RFID or NFC interfaces. Ensure the host circuitry supports the specified 4.5 V to 5.5 V operating voltage and accommodates the HCMOS/TTL output drive capability within the designated footprint constraints.

Part Context

This part belongs to the LFSPXO series of standard oscillators manufactured by IQD Frequency Products. These components are designed to provide reliable clock signals for digital circuits, offering a balance of performance and size for modern embedded applications.

Replacement Considerations

Cross-reference with other 13.56 MHz HCMOS oscillators in a 4-SMD package. Verify pinout compatibility and electrical specifications before substituting.
