18QHTF21-29.973-OE

Oscillators Overview

The 18QHTF21-29.973-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 29.973 MHz and utilizes LVCMOS output logic. The device is designed for low voltage applications with a supply voltage of 1.8V. It features an Enable/Disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. This series is part of Mercury's quartz type product line, engineered for precise frequency control in electronic circuits.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated Enable/Disable pin for power management
• Compact 4-SMD No Lead surface mount package
• Standard frequency stability for general clocking

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring stable clock signals
• Consumer electronics with space-constrained designs

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead footprint matches your PCB layout guidelines. Check for any specific operating temperature range limitations if used in extreme environments. Cross-reference the OE suffix with manufacturer documentation to confirm enable/disable functionality availability.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint oscillator with enable control is required. The 29.973 MHz frequency is suitable for video-related timing or specific baud rate generation. Consider the LVCMOS output swing compatibility with downstream logic levels. Evaluate the thermal performance within the 4-SMD package for your application's heat dissipation needs. Compare against other Mercury series options if different frequencies or packages are needed.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronic Industrial Co., Ltd, a pioneer in Taiwan's crystal industry since 1973. The series focuses on quartz-based frequency control products. It complements Mercury's broader portfolio including differential oscillators and SMD crystals. The company specializes in low EMI spread spectrum solutions alongside standard oscillators.

Oscillators Replacement Considerations

Direct substitutes must match the 29.973 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility for the OE pin. Check equivalent frequency stability and phase noise specifications. Consult Mercury Electronics for official cross-reference lists.
