18QHTF21-19.6416-PD

Oscillators Overview

The 18QHTF21-19.6416-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 19.6416 MHz and utilizes LVCMOS output logic levels. The device is designed for operation with a supply voltage of 1.8V. It features a Standby mode, also referred to as Power Down functionality, allowing for energy conservation when the oscillator is not actively driving the load. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Oscillators Feature Summary

• Supports LVCMOS output interface for digital circuit compatibility
• Includes Standby (Power Down) capability for power management
• Utilizes 1.8V supply voltage operation
• Available in 4-SMD, No Lead surface-mount package

Oscillators Applications

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD, No Lead footprint matches your PCB layout constraints. Cross-reference the part number suffix PD with manufacturer documentation to confirm any specific packaging or testing variations.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS output compatibility. The inclusion of a standby mode makes it suitable for battery-powered or power-sensitive applications. Consider the 4-SMD, No Lead package size for space-constrained designs. Verify that the 19.6416 MHz frequency meets the timing requirements of the target digital logic or communication protocol.
