18QHTF21-32.333-PD

Oscillators Overview

The 18QHTF21-32.333-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a frequency of 32.333 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down function via standby control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Provides standard LVCMOS output signals

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply requirement aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 32.333 MHz reference is required in space-constrained designs. The 1.8V supply voltage makes it suitable for modern low-power digital circuits. The integrated power-down feature allows for dynamic power management strategies in battery-operated applications where standby current reduction is critical.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized 2.0x1.6mm footprint. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-output variants in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 32.333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical characteristics such as phase noise and jitter if the application demands high precision.
