18QHTF21-33.000-OE

Oscillators Overview

The 18QHTF21-33.000-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 33 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features an enable/disable pin for active power state control
• Utilizes a small form factor surface-mount package

Oscillators Applications

• Embedded systems requiring precise timing references
• Consumer electronics with space constraints
• Industrial control modules needing stable clock signals

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and electrical characteristics match the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the enable/disable functionality is supported by the controlling microcontroller or logic circuit.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard 33 MHz frequency. The LVCMOS output is suitable for direct interfacing with CMOS-based logic families. Consider the 2.0x1.6 mm footprint for PCB layout density. The enable feature allows for dynamic power saving in battery-operated devices.

Oscillators Part Context

Mercury Electronic Ind. Co., Ltd specializes in frequency control products including quartz crystals and oscillators. This part belongs to their XO series, designed for general-purpose timing applications. The company provides various packaging options and voltage levels within this product line to meet diverse electronic design needs.

Oscillators Replacement Considerations

Direct substitutes must match the 33 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility for the enable signal. Cross-reference with other manufacturers offering similar small-footprint oscillators if availability is constrained.
