18QHTF21-4.87424-PD

Oscillators Overview

The 18QHTF21-4.87424-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 4.87424 MHz and utilizes an LVCMOS output interface. The device is designed for a supply voltage of 1.8V and features a standby power-down mode to reduce consumption during inactivity. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount assembly.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Supports standby power-down mode for energy efficiency
• Compact 4-SMD no-lead package design

Oscillators Applications

• General-purpose timing circuits requiring precise clock signals
• Embedded systems utilizing low-voltage logic interfaces
• Portable electronic devices where space constraints are critical

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 1.8V logic applications. The LVCMOS output ensures direct interfacing with microcontrollers or FPGAs without additional level shifting. Consider the standby feature if power management is a priority in the target application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a consistent small form factor. The 'PD' suffix typically indicates the presence of a power-down control pin, allowing for active and inactive states.

Oscillators Replacement Considerations

Direct substitutes must match the 4.87424 MHz frequency, 1.8V operating voltage, LVCMOS output type, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as jitter and phase noise before swapping manufacturers.
