LFSPXO082179

Overview

LFSPXO082179 is a standard clock oscillator from the IQXO-542 series by IQD Frequency Products. It operates at a nominal frequency of 30 MHz with an HCMOS output format. The device supports a supply voltage of 1.8 V and features a standby (power down) function to reduce power consumption. It utilizes a crystal as the basic resonator and is housed in a compact 4-SMD, no lead surface mount package measuring 2.00 mm x 1.60 mm x 0.80 mm. The unit offers a frequency stability of ±25 ppm and functions within a temperature range of -20°C to +70°C.

Feature Summary

• Supports hardware standby mode for power reduction
• Compact ceramic package with hermetically sealed metal lid
• HCMOS output compatible with digital logic interfaces

Applications

• Portable audio equipment requiring precise timing
• Low-power IoT sensor nodes
• Consumer electronics with strict size constraints

Procurement Notes

Verify the specific operating temperature range and supply voltage requirements against the target application design. Confirm that the 1.8V supply rail can maintain stable operation under all load conditions. Ensure the PCB layout accommodates the 4-SMD footprint dimensions accurately to prevent soldering defects during assembly.

Selection Notes

Select this component when a small form factor and low voltage operation are critical. The 30 MHz frequency suits general digital clocking needs. Consider the ±25 ppm stability sufficient for most consumer applications. Evaluate the standby current if battery life is a primary design constraint compared to continuous operation modes.

Part Context

This oscillator belongs to the IQXO-542 series, designed for space-constrained applications. It replaces larger through-hole or standard SMD oscillators where board real estate is limited. The series emphasizes low power consumption and high reliability through its ceramic construction and metal lid sealing.

Replacement Considerations

Direct substitutes include LFSPXO082221 and LFSPXO082174. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement part matches the required frequency and output drive strength.
