18QHTF21-4.800-OE

Oscillators Overview

The 18QHTF21-4.800-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fundamental frequency of 4.8 MHz and utilizes LVCMOS output logic levels. The device requires a 3.3V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package suitable for surface mount applications.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable/disable pin for power control
• Surface mount 4-SMD no lead package design

Oscillators Applications

• General purpose timing circuits
• Digital signal processing systems
• Communication equipment clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to confirm voltage and package variations. Ensure the component matches the required frequency tolerance and load capacitance specifications for the target circuit design before procurement.

Oscillators Selection Notes

Select this component when a low-cost, standard frequency XO is required for 3.3V logic systems. Consider the 4-SMD footprint constraints and LVCMOS drive requirements. Verify that the ±50ppm stability typical for this series meets the system jitter budget.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with LVCMOS outputs. The -OE suffix typically denotes specific packaging or tape-and-reel configurations as defined by the manufacturer's catalog.

Oscillators Replacement Considerations

Direct substitutes include other 4.8 MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Epson or SiTime, provided voltage and pinout compatibility are verified.
