18QHTF21-57.425-PD

Overview

The 18QHTF21-57.425-PD is a quartz crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 57.425 MHz with an LVCMOS output logic level. The device is designed for a supply voltage of 1.8V and includes a standby (power down) function to reduce power consumption when not in use. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode for power management
• Utilizes LVCMOS output interface

Applications

• Consumer electronics timing circuits
• Portable communication devices
