Overview
The 18QHTF21-6.2832-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 6.2832 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.5mm x 2.0mm.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes power-down functionality to reduce current consumption during standby
- Utilizes a leadless surface-mount package for automated assembly
Applications
- Battery-powered portable electronic devices
- Digital signal processing circuits
- Communication equipment requiring precise timing
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The integrated power-down feature makes it suitable for applications demanding active management of power consumption. Verify that the 6.2832 MHz frequency meets the specific clocking needs of the target circuit design.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a supplier specializing in quartz crystals and oscillators. The series typically offers various frequencies within a standardized small outline package format, providing consistent mechanical footprints across different clock speeds.
Replacement Considerations
Consult the manufacturer's cross-reference list for direct substitutes. Ensure any replacement maintains the 1.8V supply requirement, LVCMOS output type, and identical 2.5x2.0mm package dimensions to fit existing board layouts.
