FCXO-07F38.40MVdd0.9V50ppm-40C+105C-B

Oscillators Overview

The FCXO-07F38.40MVdd0.9V50ppm-40C+105C-B is a 38.4 MHz standard CMOS crystal oscillator manufactured by River Eletec Corporation. It operates with a supply voltage of 0.9V and features a frequency stability of ±50 ppm across the industrial temperature range of -40°C to +105°C. The device utilizes a 4-SMD, No Lead package and includes a standby function for power management. A 0.01 µF bypass capacitor is required between VDD (Pin #4) and Ground (Pin #2) for operational stability.

Oscillators Feature Summary

• CMOS output signal generation
• Standby power down capability
• Industrial temperature range operation

Oscillators Applications

• General purpose timing circuits
• Embedded systems requiring low power
• Industrial control equipment

Oscillators Procurement Notes

Verify the specific voltage suffix (0.9V) and tolerance (50ppm) against design requirements. Confirm the package type matches the PCB footprint. Ensure the temperature range meets environmental specifications. Check for the required bypass capacitor in the bill of materials.

Oscillators Selection Notes

Select this component when a 38.4 MHz clock source is needed with low voltage operation. Consider the 50 ppm stability limit for system timing accuracy. Evaluate the 4-SMD package size for space constraints. Verify compatibility with the target logic family voltage levels.

Oscillators Part Context

This part belongs to the FCXO-07 series of ultra-low supply voltage oscillators from River Eletec. The series offers various frequencies and voltage options. The 'B' suffix typically denotes specific packaging or tape/reel configuration. Other variants exist with different voltages like 1.0V or 1.2V.

Oscillators Replacement Considerations

Direct substitutes include other FCXO-07 variants with matching frequency and package. Cross-reference with similar 4-SMD CMOS oscillators from other manufacturers if availability is an issue. Ensure pinout and electrical characteristics are compatible.
