18QHTF21-40.296-OE

Oscillators Overview

The 18QHTF21-40.296-OE is a 40.296 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and features an Enable/Disable control function. The device utilizes LVCMOS output logic levels for digital interfacing. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Integrated enable/disable functionality for power management
• LVCMOS output compatibility for standard digital logic interfaces
• Compact 2.0x1.6 mm surface-mount footprint

Oscillators Applications

• Portable electronic devices requiring low-power timing
• Embedded systems utilizing LVCMOS logic families
• Consumer electronics with space-constrained PCB layouts

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the Enable/Disable pin configuration matches your control logic to ensure proper operation during standby modes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 40.296 MHz reference frequency. The small 2.0x1.6 mm package makes it suitable for high-density board designs. Consider the LVCMOS output swing if interfacing directly with microcontrollers or FPGAs without level shifting.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in Taiwan producing crystals and oscillators. This specific model represents a standard XO variant within their portfolio of surface-mount timing solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 40.296 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm SMD package. Verify electrical parameters such as phase noise and jitter specifications to ensure functional equivalence in sensitive timing circuits.
