18QHTF21-11.051-PD

Overview

The 18QHTF21-11.051-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.0592 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. This component is suitable for applications requiring precise clock signals in low-power electronic systems.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power management
• Compact surface-mount package design

Applications

• General purpose clock signal generation
• Low-power embedded systems
• Digital communication interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required for your manufacturing standards.

Selection Notes

Select this model when a 11.0592 MHz clock source is required with LVCMOS outputs. Consider the 1.8V operating voltage and the availability of a power-down feature for battery-operated devices. The small 2.0x1.6mm package makes it suitable for space-constrained designs. Compare against other frequencies in the 18QHTF21 series if different timing is needed.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with LVCMOS outputs and 1.8V operation. Similar parts include the 18QHTF21-8.000-PD and 18QHTF21-51.200-PD, which share the same package and electrical characteristics but differ in frequency.

Replacement Considerations

Direct substitutes may include other 11.0592 MHz XO components with LVCMOS outputs and 1.8V operation in a 4-SMD no-lead package. Verify pinout compatibility and electrical specifications before substitution.
