18QHTF21-58.632099-PD

Overview

The 18QHTF21-58.632099-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 58.632099 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function. It is housed in a 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby and power-down capabilities
• Provides standard LVCMOS output logic

Applications

• General electronic circuits requiring precise clock signals
• Embedded systems utilizing LVCMOS interfaces
• Portable devices benefiting from low-power standby modes

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your intended environmental conditions.

Selection Notes

Select this component when a 58.632099 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V supply constraint and the availability of power-down features for energy management. Evaluate the compact 2.0x1.6mm package size against available board space. Compare performance metrics such as phase noise and stability if critical for your application timing requirements.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a small form factor. The 'PD' suffix indicates the inclusion of a power-down pin or functionality, distinguishing it from standard continuous-operation variants in the same package family.

Replacement Considerations

Direct substitutes must match the 58.632099 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical characteristics and pinout compatibility before substitution.
