18QHTF21-19.600-OE

Oscillators Overview

The 18QHTF21-19.600-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 19.6 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning at a supply voltage of 1.8V. A key functional attribute is the inclusion of an enable/disable control pin, allowing for power management in systems requiring intermittent clock signals. The component is housed in a compact 4-SMD, No Lead package with dimensions corresponding to the 2016 metric size, suitable for surface-mount assembly processes.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Timing and clock signal generation in electronic devices
• Systems requiring low-voltage 1.8V operation
• Applications necessitating power-saving clock enable features

Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's official documentation to confirm the exact enable/disable configuration and tolerance specifications. Ensure that the 1.8V supply voltage requirement aligns with the target system design. Confirm the 4-SMD no-lead package dimensions match the PCB footprint requirements before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a 19.6 MHz clock source is required with LVCMOS compatibility. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. The enable/disable feature should be considered if power conservation during inactive periods is a design priority. Verify that the 2016 package size fits within the available board space constraints.
