18QHTF21-16.552-PD

Oscillators Overview

The 18QHTF21-16.552-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 16.552 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby function for power down 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 LVCMOS output logic for digital interface compatibility
• Includes Standby mode capability for power management
• Utilizes a leadless SMD package for surface mount assembly

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded applications utilizing standard XO interfaces

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD No Lead footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 16.552 MHz timing source is required for low-voltage digital logic. The choice depends on the necessity for LVCMOS outputs and the availability of a 1.8V power supply. Consider the physical constraints of the 2.0x1.6mm package size relative to the available board space and thermal requirements of the application environment.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of standard crystal oscillators. The series typically offers various frequencies within a small form factor. The 'PD' suffix indicates the inclusion of a Power Down or Standby pin functionality, distinguishing it from continuous-operation variants within the same product line.

Oscillators Replacement Considerations

Direct substitutes must match the 16.552 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if specified in the original design documentation.
