18QHTF21-11.288-OE

Overview

The 18QHTF21-11.288-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.288 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features enable/disable control functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The unit supports an operating temperature range of -40°C to +85°C and maintains a frequency stability of ±50ppm.

Feature Summary

• Supports Enable/Disable control for power management
• Compact 4-SMD No Lead surface mount package
• LVCMOS output logic compatibility

Applications

• Embedded systems requiring precise clock signals
• Communication equipment timing references
• Consumer electronics internal clocking

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm enable/disable functionality and pinout configuration. Ensure the 1.8V supply requirement aligns with target system voltage rails. Confirm package footprint matches 2.0x1.6mm SMD land pattern specifications before integration.

Selection Notes

Select this component when a low-voltage 1.8V XO is required with active control capabilities. The 11.288 MHz frequency is suitable for baud rate generation in serial communications. Consider the ±50ppm stability for applications tolerant to moderate frequency drift over temperature ranges.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, designed for high-density PCB layouts. The series offers various frequencies within the same small form factor, allowing design flexibility while maintaining consistent electrical characteristics across different clock speeds.

Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in 2.0x1.6mm packages. Verify frequency tolerance and enable pin logic polarity match. Cross-reference with Mercury's 3QHTF21 series if voltage or size constraints differ.
