18QHTF21-93.333333-PD

Overview

The 18QHTF21-93.333333-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 93.333333 MHz with an LVCMOS output signal. The device functions at a supply voltage of 1.8V and features a standby (power down) mode for energy efficiency. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6mm. This component is part of the QuikXO series, designed for fast delivery and reliable clock generation in electronic circuits.

Feature Summary

• Supports standby power down mode to reduce current consumption
• Utilizes LVCMOS output interface for digital logic compatibility
• Compact 4-SMD no lead surface mount package design

Applications

• General purpose clock generation in embedded systems
• Timing reference for digital communication interfaces
• Consumer electronics requiring low profile oscillators

Procurement Notes

Verify that the specific suffix PD indicates the RoHS compliant packaging variant as documented. Confirm the operating temperature range and load capacitance requirements against the target circuit design before ordering. Ensure the 1.8V supply voltage aligns with the system power rails. Check the datasheet for precise electrical characteristics such as jitter and phase noise specifications relevant to the application.

Selection Notes

Select this component when a 93.333333 MHz clock source is required with a 1.8V supply constraint. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Consider the LVCMOS output level if interfacing directly with standard logic families. The standby feature is advantageous for battery-powered applications requiring power management capabilities.

Part Context

This oscillator belongs to Mercury's QuikXO series, which focuses on fast-delivery CMOS output clock solutions. Mercury Electronics has been manufacturing frequency control products since 1973, specializing in quartz crystals and oscillators. The 18QHTF21 series represents their standard XO offerings with various frequency options available in the same package form factor.

Replacement Considerations

Compatible substitutes include other 93.333333 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as frequency stability and output swing before substitution.
