18QHTF21-17.3317-PD

Oscillators Overview

The 18QHTF21-17.3317-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 17.3317 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 package with dimensions of 2.0x1.6 mm, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby mode for power reduction
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing circuits
• Communication equipment clock sources
• Embedded system timing references

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a precise 17.3317 MHz reference is required with low power consumption capabilities. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 1.8V operating voltage constraint and the availability of the standby feature for battery-powered or energy-efficient designs requiring periodic sleep modes.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequency options within a small form factor. The 'PD' suffix typically indicates the inclusion of a power-down control pin, allowing the user to disable the output to save power when the oscillator is not actively needed in the system.

Oscillators Replacement Considerations

Direct replacements must match the 17.3317 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical to the application.
