18QHTF21-112.192-PD

Overview

The 18QHTF21-112.192-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a fixed frequency of 112.192 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output logic interface

Applications

• Digital signal processing systems
• Communication equipment requiring precise clocking
