18QHTF21-10.83322-OE

Overview

The 18QHTF21-10.83322-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.83322 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is suitable for applications requiring precise timing signals in low-voltage digital systems.

Feature Summary

• Integrates LVCMOS output logic for direct interfacing with digital circuits
• Features an enable/disable pin for power management and signal control
• Utilizes a surface-mount package design for automated assembly processes

Applications

• Clock generation for microprocessors and microcontrollers
• Timing reference for communication interfaces
• Synchronization in consumer electronic devices

Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm active status and exact pinout configuration. Ensure that the 1.8V supply requirement aligns with the target system's voltage rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues or damage.

Selection Notes

Select this component when a stable 10.83322 MHz clock source is required for 1.8V logic families. Consider the small 2.0x1.6mm footprint if board space is limited. Evaluate the need for the enable/disable feature for power-sensitive designs. Compare performance metrics such as jitter and stability against other oscillators in the same series if stricter timing specifications are necessary.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized small outline package. The series typically supports multiple supply voltages and output types. The 18QHTF21-10.83322-OE specifically targets applications needing a precise 10.83322 MHz frequency in a low-profile surface-mount form factor.

Replacement Considerations

Direct substitutes may include other 10.83322 MHz XO components from different manufacturers provided they match the 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify electrical parameters and pin assignments before substitution.
