18QHTF21-27.064-PD

Oscillators Overview

The 18QHTF21-27.064-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.064 MHz with an LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby (power down) function. It is housed in a surface-mount package with dimensions of 2.0 mm by 1.6 mm.

Oscillators Feature Summary

• Supports standard LVCMOS output logic for digital interfacing
• Includes a standby mode to reduce power consumption during inactive periods
• Designed for compact applications with a small 2.0x1.6 mm footprint

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for low-voltage digital circuits
• Portable electronic devices requiring minimal power usage

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6 mm package size fits within the designated PCB area. Check for any specific operating temperature range limitations required by your application environment.

Oscillators Selection Notes

Select this component when a precise 27.064 MHz timing source is needed for low-voltage logic interfaces. Consider the standby feature if power management is critical. The small form factor makes it suitable for space-constrained designs. Ensure compatibility with LVCMOS input thresholds of the receiving components.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltages, including 1.8V options. The PD suffix likely indicates a specific packaging or tape-and-reel configuration. Mercury Electronics has extensive experience in quartz crystal manufacturing since 1973.

Oscillators Replacement Considerations

Direct substitutes may include other 27.064 MHz LVCMOS oscillators in a 2.0x1.6 mm package with 1.8V operation. Verify pinout compatibility and electrical specifications such as jitter and phase noise. Alternative parts from different manufacturers must match the standby functionality and output drive strength.
