18QHTF21-11.0592-PD

Overview

The 18QHTF21-11.0592-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 11.0592 MHz with an LVCMOS output signal. The device supports a supply voltage of 1.8V and includes a standby or power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The unit offers a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports low-voltage operation at 1.8V for energy-efficient system integration
• Includes standby and power-down capabilities to reduce consumption during idle states
• Provides stable clock signals via LVCMOS interface for digital circuit synchronization

Applications

• Embedded systems requiring precise timing references
• Communication modules needing standard clock frequencies
• Portable electronic devices utilizing low-power components

Procurement Notes

Verify the specific frequency tolerance and temperature range requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards. Validate lead times with the supplier as availability may fluctuate.

Selection Notes

Select this component when a 11.0592 MHz clock source is necessary for serial communication protocols such as UART. Consider the ±50ppm stability limit for applications sensitive to timing drift. The 1.8V requirement dictates compatibility with modern low-voltage logic families. Evaluate the small 2.0x1.6mm package size against available board space. Compare performance against other oscillators if higher stability or different voltage levels are needed.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically features standard frequencies and low-profile packages suitable for dense PCB designs. Mercury Electronic Ind. Co., Ltd. has a long history in quartz crystal manufacturing, positioning this component within their established portfolio of frequency control products.

Replacement Considerations

Direct substitutes must match the 11.0592 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent stability ratings and temperature ranges. Cross-reference pinouts and electrical characteristics to ensure functional compatibility without redesigning the host circuit.
