18QHTF21-74.92788-OE

Overview

The 18QHTF21-74.92788-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 74.92788 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• LVCMOS output logic interface
• Enable/Disable control functionality
• Standard XO type with fixed frequency

Applications

• General electronic equipment clock generation
• Embedded system timing references
• Consumer electronics signal processing

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and voltage requirements. Ensure the 1.8V supply aligns with target circuit design. Confirm the 4-SMD no-lead package dimensions match PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when a precise 74.92788 MHz reference is required with low-voltage operation. The LVCMOS output is compatible with standard digital logic families. Consider the enable pin utility for power-sensitive applications requiring dynamic clock control during idle states.

Part Context

This part belongs to the 18QHTF21 series of SMD oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'OE' suffix likely denotes specific operational characteristics or packaging variants within the manufacturer's catalog, distinguishing it from other suffixes like 'PD'.

Replacement Considerations

Direct substitutes must match the 74.92788 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify enable/disable functionality compatibility. Cross-reference with Mercury Electronics' current product list for equivalent series members.
