18QHTF21-22.59724-OE

Oscillators Overview

The 18QHTF21-22.59724-OE is a fixed-frequency crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 22.59724 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 2.0mm x 1.6mm. This surface-mount oscillator is suitable for space-constrained electronic designs requiring precise clock signals.

Oscillators Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated enable/disable functionality for power management
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General purpose clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring small form factor oscillators

Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm pinout and electrical tolerances. Ensure the 1.8V supply requirement aligns with the target system's voltage rails. Confirm that the LVCMOS output swing is compatible with the receiving logic inputs. Check for any RoHS compliance documentation if required by the end product regulations.

Oscillators Selection Notes

Select this component when a 22.59724 MHz clock source is strictly required. The 1.8V operating voltage makes it suitable for modern low-power portable devices. The enable pin allows for dynamic power saving during idle periods. Consider the 2.0x1.6mm footprint constraints during PCB layout planning to ensure adequate soldering area for the no-lead package type.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which focuses on quartz-based clock oscillators. The brand has a history of manufacturing frequency control products including crystals and TCXOs since 1973. The 18QHTF21 series represents their standard fixed-frequency offerings in small SMD packages, targeting cost-sensitive and space-efficient applications.

Oscillators Replacement Considerations

The model 18QHTF21-22.59724-PD from the same manufacturer offers identical electrical specifications but may differ in packaging or reel configuration. Verify that the replacement maintains the exact 22.59724 MHz frequency and 1.8V supply requirements before substitution.
