18QHTF21-13.52875-PD

Overview

The 18QHTF21-13.52875-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 13.52875 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Compact 4-SMD no lead package design

Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Confirm that the 1.8V supply requirement aligns with the target system design. Ensure the 4-SMD package dimensions fit within the designated PCB footprint constraints to avoid assembly issues.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The inclusion of a power-down feature makes it suitable for battery-powered or energy-efficient designs. Verify that the standard XO stability meets the jitter and accuracy requirements of the application.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, all sharing the same compact SMD form factor. The 'PD' suffix typically indicates the presence of a power-down control pin or feature.

Replacement Considerations

Direct substitutes must match the 13.52875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before substitution.
