18QHTF32-14.649-PD

Oscillators Overview

The 18QHTF32-14.649-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 14.649 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a power-down feature for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.2x2.5 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down functionality for energy management
• Utilizes standard LVCMOS output interface

Oscillators Applications

• General-purpose digital clock generation
• Embedded system timing references
• Consumer electronics requiring precise frequency sources

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates Power Down capability rather than other variants like 'OE' (Enable/Disable). Confirm the operating voltage matches the 1.8V requirement of the target circuit design. Ensure the 4-SMD No Lead package footprint aligns with the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 14.649 MHz reference is required with low power consumption capabilities. The choice depends on the necessity for a power-down state to extend battery life or reduce thermal output. Consider the physical size constraints imposed by the 3.2x2.5 mm package relative to available board space.

Oscillators Part Context
