18QHTF21-27.505-OE

Oscillators Overview

The 18QHTF21-27.505-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 27.505 MHz. It utilizes LVCMOS output logic and supports a supply voltage range compatible with 1.8V operation, featuring integrated enable and disable control capabilities. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, designed for surface-mount applications requiring precise timing signals in space-constrained electronic circuits.

Oscillators Feature Summary

• Supports active high/low enable and disable functionality for power management
• Delivers stable LVCMOS clock signals with low jitter characteristics
• Utilizes a leadless SMD package optimized for automated surface-mount assembly

Oscillators Applications

• High-speed digital signal processing systems
• Communication equipment requiring precise clock synchronization
• Embedded systems with strict power consumption constraints

Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm enable/disable pin configuration and voltage tolerance. Ensure the ordering part number matches the required 27.505 MHz frequency exactly, as minor variations in the base model may indicate different electrical specifications or packaging types. Cross-reference the 4-SMD no-lead footprint with your PCB design guidelines to guarantee mechanical compatibility.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V interface is required alongside active power control features. The 2.0x1.6mm form factor makes it suitable for dense layouts where larger oscillators cannot fit. Consider the LVCMOS output swing requirements of the receiving circuitry to ensure signal integrity without additional buffering components.

Oscillators Part Context

This oscillator belongs to the 18QHTF series from Mercury Electronics, which focuses on miniaturized clock solutions. The series typically offers various frequency options within a standardized small outline package. The '27.505' designation specifies the unique resonant frequency, distinguishing it from other variants in the same physical package family that may operate at different frequencies or voltages.

Oscillators Replacement Considerations

Direct substitutes include the 3QHTF21-27.505-PD, which shares similar frequency and package dimensions but may differ in voltage levels or pinout configurations. Always verify electrical parameters and pin assignments before swapping components to avoid circuit malfunction.
