18QHTF21-33.924-PD

Oscillators Overview

The 18QHTF21-33.924-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 33.924 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features a power-down function and is housed in a 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes standby capability via power-down control
• Utilizes a compact surface-mount package design

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded devices requiring precise frequency stability

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your intended environmental conditions.

Oscillators Selection Notes

Select this component when a 33.924 MHz clock source is required for LVCMOS-compatible logic families. The choice is driven by the need for a low-voltage (1.8V) operation and a small form factor suitable for space-constrained designs. Consider the power-down feature if energy efficiency during idle states is a priority for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co. Ltd, which specializes in quartz crystal frequency control products. The series typically offers various frequencies within a standardized 2.0x1.6mm SMD package.
