18QHTF21-20.1416-PD

Oscillators Overview

The 18QHTF21-20.1416-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 20.1416 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby capability for power management
• Utilizes LVCMOS output interface

Oscillators Applications

• General purpose clock signal generation
• Embedded systems requiring low-profile oscillators
• Portable electronic devices

Oscillators Procurement Notes

Verify the specific ordering suffix and package variant against official datasheets before procurement. Ensure compatibility with 1.8V supply rails and LVCMOS input requirements of the target circuit. Confirm that the 4-SMD no-lead form factor fits the designated footprint on the printed circuit board layout.

Oscillators Selection Notes

Select this component when a precise 20.1416 MHz reference is required in space-constrained designs. Consider the 1.8V operating voltage and LVCMOS drive strength relative to downstream logic inputs. Evaluate the thermal and mechanical constraints associated with the small 2.0x1.6mm surface-mount package during PCB design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized small outline package. Mercury Electronics is a recognized manufacturer of frequency control products, including crystals and oscillators, with a history dating back to 1973.

Oscillators Replacement Considerations

Direct substitutes must match the 20.1416 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package dimensions. Verify pinout compatibility and electrical characteristics with alternative manufacturers offering similar surface-mount XO components.
