18QHTF21-7.160-PD

Overview

The 18QHTF21-7.160-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.160 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead surface-mount package with dimensions of 2.00mm x 1.60mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby/power-down functionality
• Utilizes LVCMOS output interface

Applications

• General electronic circuits requiring precise timing
• Embedded systems utilizing LVCMOS logic
• Portable devices requiring low-power oscillators

Procurement Notes

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

Selection Notes

Select this component when a 7.160 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint and the need for a power-down feature. The small 2.0x1.6mm package size makes it suitable for space-constrained designs compared to larger oscillator packages.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD no-lead form factor. The series is designed for applications needing reliable timing solutions with low profile and power efficiency characteristics typical of modern surface-mount technology components.

Replacement Considerations

Direct substitutes must match the 7.160 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as jitter and phase noise if critical to the application.
