18QHTF21-35.090-PD

Oscillators Overview

The 18QHTF21-35.090-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 35.09 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature 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 low-voltage operation at 1.8V
• Includes standby mode for power reduction
• Utilizes LVCMOS output interface

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Consumer electronics circuitry

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a precise 35.09 MHz reference is required in space-constrained designs. The choice is driven by the need for low-power consumption via the standby function and compatibility with 1.8V logic families. Consider the small form factor as a primary advantage for dense board layouts.

Oscillators Part Context

This model belongs to the Mercury Electronics SMD oscillator series, characterized by small footprints and low voltage operation. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-output variants within the same physical package family.

Oscillators Replacement Considerations

Direct replacements must match the 35.09 MHz frequency, 1.8V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD no-lead package to ensure interchangeability without redesigning the host circuit board.
