18QHTF21-76.5432-OE

Overview

The 18QHTF21-76.5432-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 76.5432 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring 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 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Utilizes quartz crystal technology for frequency stability

Applications

• Handheld label printers
• Portable electronic devices
• Embedded systems requiring precise clock signals

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the exact packaging or tape-and-reel configuration. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm that the 4-SMD no-lead package footprint matches the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a 76.5432 MHz clock source is required for LVCMOS-compatible circuits. The 1.8V operating voltage makes it suitable for modern low-power portable electronics. Consider the small 2.0x1.6mm footprint for space-constrained designs. Verify temperature range requirements against the datasheet if operating in extreme environments.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized low-profile package. The 'OE' suffix likely denotes specific ordering or packaging details defined by the manufacturer. This series is positioned for consumer and industrial applications needing reliable timing solutions.

Replacement Considerations

Direct substitutes include other 76.5432 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution. Cross-reference with Mercury Electronics' own variants like the 18QHTF21-76.5432-PD if packaging differences exist.
