18QHTF21-24.900-PD

Oscillators Overview

The 18QHTF21-24.900-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.9 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) function to reduce power consumption when not in active use. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for space-constrained surface-mount applications.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Includes standby mode capability for power management
• Utilizes a leadless surface-mount package design

Oscillators Applications

• General clock signal generation
• Digital system timing references
• Embedded controller synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required specifications. Confirm that the package type and electrical parameters match the target design requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-profile, leadless oscillator is required for 1.8V logic systems. Ensure the application supports LVCMOS outputs and requires a standby feature for power efficiency considerations during idle periods.

Oscillators Part Context
