18QHTF21-17.215-OE

Oscillators Overview

The 18QHTF21-17.215-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 17.215 MHz and utilizes LVCMOS output logic levels. The device supports an enable/disable control function via a supply voltage of 1.8V. It 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 clock signals.

Oscillators Feature Summary

• Supports active enable and disable control functionality
• Provides standard LVCMOS output signal compatibility
• Utilizes a low-profile 4-SMD no-lead surface mount package

Oscillators Applications

• Embedded system clock generation
• Digital signal processing timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an enable pin for power management. The small 4-SMD form factor makes it suitable for space-constrained designs. Verify that the LVCMOS output swing is compatible with the receiving logic inputs of the connected microcontroller or FPGA.

Oscillators Part Context

This part belongs to the 18QHTF21 series of high-frequency crystal oscillators from Mercury Electronics. The series typically offers various frequencies within the 1.8V operating range. The 'OE' suffix generally indicates a specific output configuration or packaging variant defined by the manufacturer's internal coding standards for this oscillator family.

Oscillators Replacement Considerations

Direct substitutes must match the 17.215 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering identical envelope dimensions and electrical specifications to ensure pin-to-pin compatibility without circuit modification.
