18QHTF21-19.968-OE

Oscillators Overview

The 18QHTF21-19.968-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 19.968 MHz and utilizes an LVCMOS output interface. The device functions with a supply voltage of 1.8V and features an Enable/Disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports active low enable/disable functionality for power optimization
• Provides stable clock signals via LVCMOS output interface
• Designed for low-voltage operation at 1.8V

Oscillators Applications

• Timing and clock signal generation in electronic devices
• Embedded systems requiring precise frequency references
• Consumer electronics utilizing low-power oscillators

Oscillators Procurement Notes

Verify the specific suffix 'OE' to confirm the presence of the enable/disable control feature, as this distinguishes it from standard variants without control pins. Ensure the operating voltage matches the 1.8V requirement of the target circuit design. Confirm the package footprint aligns with the 2.0x1.6 mm SMD no-lead specification during PCB layout validation.

Oscillators Selection Notes

Select this component when an enable/disable control mechanism is required for power management in 1.8V applications. The LVCMOS output ensures compatibility with standard digital logic interfaces. Consider the small 2.0x1.6 mm package size for space-constrained designs requiring a 19.968 MHz reference frequency source.

Oscillators Part Context

Mercury Electronics has manufactured frequency control products since 1973 and is recognized as a pioneer in the crystal industry in Taiwan. This oscillator belongs to their line of surface-mount timing devices designed for modern electronic applications requiring reliable frequency stability.
