18QHTF21-40.330-PD

Oscillators Overview

The 18QHTF21-40.330-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 40.33 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby and power-down functionality to reduce power consumption
• Designed as a standard crystal oscillator for precise timing applications

Oscillators Applications

• Digital signal processing systems requiring stable clock sources
• Communication equipment utilizing LVCMOS interfaces
• Portable electronic devices benefiting from low-voltage operation and small form factor

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific handling instructions related to the surface-mount technology.

Oscillators Selection Notes

Select this component when a 40.33 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V operating voltage for low-power designs. The small 2.0x1.6mm package is suitable for space-constrained applications. Evaluate the need for standby functionality if power management is a priority in the target system.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltages within a standardized small outline package. The 'PD' suffix indicates the inclusion of power-down capabilities, distinguishing it from standard continuous-operation variants in the same family.

Oscillators Replacement Considerations

Direct replacements must match the 40.33 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if critical. Consult manufacturer cross-reference lists for verified equivalents.
