18QHTF21-35.280-PD

Oscillators Overview

The 18QHTF21-35.280-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 35.280 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a compact surface-mount package with dimensions of 2.0mm x 1.6mm in a 4-SMD, No Lead configuration. A key functional characteristic is the inclusion of a standby or power-down mode to manage energy consumption when the oscillator is not actively driving the load.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby functionality for power management
• Utilizes a small-footprint surface-mount package

Oscillators Applications

• Embedded systems requiring precise timing references
• Digital signal processing circuits
• Communication modules utilizing standard clock interfaces

Oscillators Procurement Notes

Verify the specific part number against official Mercury Electronics documentation to ensure accuracy regarding the 35.280 MHz frequency and 1.8V operating voltage. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Ensure that the LVCMOS output type aligns with your target circuit's input specifications before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V compatible oscillator is required for space-constrained designs. The choice depends on the need for a standard LVCMOS output rather than differential signaling. Consider the thermal and mechanical constraints of the 2.0x1.6mm package during layout planning. Validate that the frequency stability meets system timing tolerances using the manufacturer's datasheet.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics 18QHTF series, which focuses on low-voltage, high-frequency performance in miniature packages. The series is characterized by its use of quartz resonators for stable timing. The 'PD' suffix typically indicates the presence of a power-down control feature, distinguishing it from continuously running variants within the same family.
