18QHTF21-35.46895-PD

Oscillators Overview

The 18QHTF21-35.46895-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 35.46895 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, featuring a supply voltage of 1.8V. It includes a standby or power-down function to manage energy consumption effectively. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode for power management efficiency
• Utilizes a lead-free SMD package for automated assembly

Oscillators Applications

• Consumer electronics requiring precise timing signals
• Communication equipment utilizing standard clock frequencies
• Embedded systems needing low-power oscillators

Oscillators Procurement Notes

Verify the specific suffix 'PD' against official Mercury Electronics documentation to confirm the presence of the power-down feature. Ensure the operating temperature range aligns with system requirements. Cross-reference the 4-SMD no-lead footprint with PCB design guidelines to prevent soldering defects during manufacturing.

Oscillators Selection Notes

Select this model when a 35.46895 MHz frequency is required with 1.8V operation. Consider the LVCMOS output type for direct interfacing with digital logic. Evaluate the 2.0x1.6mm package size against available board real estate. Confirm that the standard frequency stability meets the application's jitter and drift specifications.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, focusing on small-form-factor timing solutions. The '18' prefix typically indicates the 1.8V supply voltage, while 'QHTF21' denotes the specific package and performance class within their product line. It serves as a fundamental clock source for synchronous digital circuits.

Oscillators Replacement Considerations

Direct substitutes must match the 35.46895 MHz frequency, 1.8V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD no-lead package. Check if alternative manufacturers offer equivalent frequency stability and phase noise characteristics for seamless integration.
