18QHTF21-15.200-PD

Oscillators Overview

The 18QHTF21-15.200-PD is a 15.2 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates with a standard LVCMOS output signal and supports a supply voltage of 1.8V. The device features a power-down function for standby mode control. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Standard LVCMOS output interface
• Integrated power-down capability for standby operation
• Compact surface-mount package design

Oscillators Applications

• General digital circuit clocking
• Embedded system timing references
• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 15.2 MHz reference is required with minimal power usage. The integrated power-down feature makes it suitable for battery-operated applications where standby current reduction is critical. Verify compatibility with the host controller's input voltage levels and ensure the small form factor fits within the constrained enclosure space.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, typically utilizing standard LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down pin or function, allowing for active standby management in the final application.

Oscillators Replacement Considerations

Direct substitutes include other 15.2 MHz XO models with identical 1.8V LVCMOS output and 4-SMD 2.0x1.6mm packages. Verify pinout compatibility and electrical parameters such as phase noise and jitter before swapping. Alternative parts must support the same power-down functionality if standby operation is required.
