18QHTF21-3.512-OE

Oscillators Overview

The 18QHTF21-3.512-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 3.512 MHz with an LVCMOS output logic level. The device supports a supply voltage range and features a dedicated Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output interface compatible with standard digital logic circuits
• Integrated enable/disable pin for active power state control
• Standard crystal resonator base for stable frequency generation

Oscillators Applications

• General timing clock signal generation
• Embedded system microcontroller clocks
• Digital communication interface synchronization

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Ensure the LVCMOS voltage levels align with your target logic family to prevent signal integrity issues or damage.

Oscillators Selection Notes

Select this component when a precise 3.512 MHz reference is required with low power consumption capabilities. The enable/disable feature makes it suitable for battery-operated devices requiring sleep modes. Consider the ±50ppm stability typical for this series if tight frequency tolerance is critical for your application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within the standard XO category. The 'OE' suffix typically denotes specific packaging or tape-and-reel configuration options provided by the manufacturer for automated assembly processes.

Oscillators Replacement Considerations

Direct substitutes include other 3.512 MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Epson, NDK, or SiTime. Verify pin compatibility and electrical parameters such as current consumption and startup time when cross-referencing alternative sources.
