Overview
The 18QHTF21-12.270-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.27 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby mode with power-down capability. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6mm, suitable for surface-mount assembly.
Feature Summary
- Supports LVCMOS output signal compatibility
- Includes standby functionality with power-down control
- Operates on a single 1.8V supply voltage
Applications
- Battery-powered portable electronic devices
- Low-power consumer electronics
- General-purpose digital clock generation
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply rail meets the current consumption specifications during active operation. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions to guarantee proper soldering and mechanical stability.
Selection Notes
Select this component when a precise 12.27 MHz reference is required for systems operating at 1.8V. Consider the LVCMOS interface for direct connection to compatible digital logic. Evaluate the power-down feature if energy conservation is critical for the application's standby states.
Part Context
This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series includes various XO, TCXO, and VCXO options. Mercury Electronic has been manufacturing these components since 1973, establishing itself as a pioneer in the Taiwan crystal industry.
Replacement Considerations
Check for exact frequency match and package compatibility. Verify that alternative oscillators support LVCMOS outputs and 1.8V operation. Ensure substitute parts offer similar power-down capabilities if standby functionality is required.
