18QHTF21-32.875-PD

Oscillators Overview

The 18QHTF21-32.875-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a standard frequency of 32.875 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby function for power down control. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Features LVCMOS output logic for digital interfacing
• Includes standby capability for power management

Oscillators Applications

• General-purpose digital timing circuits
• Embedded systems requiring precise clock sources
• Portable electronics due to low voltage operation

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature when ordering. Confirm the operating temperature range and load capacitance requirements match the target circuit design. Ensure the 4-SMD no-lead package footprint aligns with the PCB layout specifications before finalizing procurement.

Oscillators Selection Notes

Select this component when a 32.875 MHz clock signal is required with low power consumption. The 1.8V supply requirement makes it suitable for modern low-voltage digital logic families. Consider the standby feature if power efficiency during idle states is a critical design parameter for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies and output types. The series is known for providing stable crystal oscillators in small form factors. The 'PD' suffix typically denotes specific operational modes or features within this product line.

Oscillators Replacement Considerations

Direct substitutes must match the 32.875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pin compatibility and electrical characteristics such as jitter and stability before swapping components.
