18QHTF21-83.665-PD

Overview

The 18QHTF21-83.665-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 83.665 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features a 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. It supports standby mode via power down functionality.

Feature Summary

• Supports low voltage operation at 1.8V
• Includes standby capability through power down control
• Utilizes compact surface-mount packaging

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring LVCMOS interfaces
• Embedded devices utilizing small form factor components

Procurement Notes

Verify the specific operating temperature range and frequency stability specifications against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with system requirements. Ensure the 4-SMD no-lead package footprint matches the design layout to avoid assembly issues.

Selection Notes

Select this component when a precise 83.665 MHz timing source is required within space-constrained designs. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 1.8V supply requirement and power down feature for energy-efficient applications where standby modes are necessary.

Part Context

This part belongs to the 18QHTF21 series of oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options in a standardized 2.0x1.6mm package. The suffix PD indicates power down functionality, distinguishing it from standard continuous operation variants within the same family.

Replacement Considerations

Direct substitutes must match the 83.665 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar small-form-factor XO solutions if availability is an issue.
