18QHTF21-24.701111-PD

Oscillators Overview

The 18QHTF21-24.701111-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.701111 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby (power down) control function. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby power down functionality for energy management
• Utilizes a surface-mount 4-SMD no lead package design

Oscillators Applications

• Digital signal processing circuits
• Communication equipment clocking
• Embedded system timing references

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the presence of the standby control feature, as variants without this suffix may lack power-down capabilities. Ensure the supply voltage matches the 1.8V requirement. Confirm the package footprint aligns with the 2.0x1.6mm SMD dimensions before integration into the PCB layout.

Oscillators Selection Notes

Select this component when a precise 24.701111 MHz reference is required with low power consumption options. The 1.8V supply voltage makes it suitable for modern low-voltage digital systems. The standby feature allows for active power management in battery-operated or energy-efficient designs requiring periodic clock gating.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage levels. The -PD suffix specifically denotes the inclusion of a power-down pin or control mechanism, distinguishing it from standard continuous-operation models within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 24.701111 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that any replacement also includes the standby/power-down functionality if required by the circuit design.
