• Supports low-voltage operation at 1.8V for energy efficiency
• Includes standby mode capability to reduce power consumption
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed in a small surface-mount package for space-constrained applications

Applications

• Battery-powered portable devices
• Embedded systems requiring precise timing
• Digital signal processing circuits
• Communication modules

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's specifications. Confirm that the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to avoid assembly issues.

Selection Notes

Select this component when a 12.032 MHz clock source is required with low power consumption capabilities. The 1.8V operating voltage makes it suitable for modern low-voltage digital logic families. Consider the standby feature if power management during idle states is critical for the application.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and package options, typically featuring LVCMOS outputs and low voltage operation. The 'PD' suffix indicates the presence of a power-down or standby control pin.

Replacement Considerations

Direct substitutes may include other 12.032 MHz LVCMOS oscillators in 2.0x1.6mm packages with 1.8V operation and standby functionality. Verify electrical parameters such as jitter, phase noise, and startup time to ensure compatibility.
