18QHTF21-27.1457-OE

Oscillators Overview

The 18QHTF21-27.1457-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 27.1457 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Provides stable clock signals via LVCMOS output interface
• Supports active enable and disable control states
• Designed for low-voltage 1.8V operation

Oscillators Applications

• Computing systems requiring precise timing references
• Communication equipment utilizing standard clock frequencies
• Embedded electronics needing compact oscillator solutions

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the exact enable/disable functionality and pinout configuration. Ensure that the 1.8V supply requirement aligns with the target circuit design before procurement. Cross-reference the 4-SMD no-lead package dimensions for accurate PCB footprint implementation.

Oscillators Selection Notes

Select this component when a 27.1457 MHz frequency is required alongside LVCMOS compatibility. Consider the 1.8V operating voltage and the need for software-controllable power states via the enable pin. Evaluate the small 2.0x1.6mm footprint against available board space constraints.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, which specializes in quartz-based frequency control products. The manufacturer has extensive experience in producing oscillators for computing and communication sectors since 1973. This specific part represents a standard solution within their portfolio of surface-mount devices.

Oscillators Replacement Considerations

The 18QHTF21-27.1457-PD is a related variant from the same series, distinguished by its standby or power-down mode capability rather than simple enable/disable. Verify functional equivalence regarding control logic before substitution.
