18QHTF21-1.10593-OE

Overview

The 18QHTF21-1.10593-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 1.10593 MHz and utilizes an LVCMOS output signal format. The device is designed for low-voltage applications, functioning 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, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Provides stable timing signals via LVCMOS output interface
• Supports active low or high enable/disable control functionality
• Operates on a single 1.8V power supply rail
• Utilizes a leadless SMD package for automated surface mounting

Applications

• Clock generation for digital logic circuits requiring 1.10593 MHz reference
• Timing source for microcontroller systems operating at 1.8V
• Synchronization modules in communication equipment using LVCMOS interfaces

Procurement Notes

Verify the specific frequency suffix matches the required 1.10593 MHz specification. Confirm the package type is 4-SMD No Lead. Ensure the supply voltage requirement aligns with the 1.8V operational limit. Check for any specific enable pin configuration requirements in the system design.

Selection Notes

Select this component when a precise 1.10593 MHz clock is needed for low-power 1.8V logic systems. The LVCMOS output ensures compatibility with standard digital inputs. The enable feature allows for power management strategies. Consider the small form factor for space-constrained designs.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within a consistent 4-SMD footprint. These oscillators are designed for general-purpose timing applications where low voltage operation and compact size are prioritized over ultra-high stability specifications.

Replacement Considerations

Direct replacements must match the 1.10593 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility before substitution. Other Mercury parts in the same series may differ only in frequency.
