18QHTF21-16.6666-PD

Oscillators Overview

The 18QHTF21-16.6666-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 16.6666 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a 1.8V supply voltage requirement. A key functional characteristic is the inclusion of a standby or power-down mode to reduce energy consumption when the oscillator is not actively driving the load. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes in modern electronic designs.
