18QHTF21-22.0586-PD

Oscillators Overview

The 18QHTF21-22.0586-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 22.0586 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby power-down capability
• Utilizes LVCMOS output logic

Oscillators Applications

• General timing applications requiring standard frequency control
• Embedded systems utilizing LVCMOS interfaces
• Portable electronics due to small form factor

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature as documented. Confirm the operating temperature range and load capacitance requirements against the official datasheet for the 18QHTF21 series before integration. Ensure the 1.8V supply rail stability meets the component's specifications.

Oscillators Selection Notes

Select this component when a precise 22.0586 MHz clock signal is required in space-constrained designs. The choice is driven by the need for LVCMOS compatibility and low-power standby modes. Consider the 2.0x1.6 mm footprint constraints and verify that the 1.8V supply is available within the target system architecture.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series is characterized by its small 2.0x1.6 mm package size and support for various frequencies. The 'PD' suffix typically denotes the inclusion of a power-down pin or function, distinguishing it from standard variants without this feature.

Oscillators Replacement Considerations

Direct replacements must match the 22.0586 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify if alternative manufacturers offer equivalent parts with identical pinout and electrical characteristics to ensure mechanical and functional interchangeability.
