Overview
The 18QHTF21-12.650-PD is a 12.65 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates at a supply voltage of 1.8V. The device features a Standby (Power Down) mode for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.
Feature Summary
- LVCMOS output interface
- Standby (Power Down) functionality
- Compact 4-SMD No Lead package
Applications
- Battery-powered portable devices
- General clock signal generation
- Embedded systems requiring low power consumption
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a precise 12.65 MHz clock signal is required with minimal power consumption. The 1.8V operating voltage makes it suitable for modern low-voltage digital circuits. The inclusion of a standby mode allows for extended battery life in portable applications compared to continuously running oscillators.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various standard frequencies. The series is characterized by its small form factor and low voltage operation. Similar models in the series include variants like 18QHTF21-50.000-PD and 18QHTF21-51.200-PD, differing primarily in their output frequencies while maintaining the same package and electrical characteristics.
Replacement Considerations
Direct substitutes may include other 12.65 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package from different manufacturers. Ensure compatibility regarding supply voltage, output drive strength, and pin configuration. Verify that any replacement part supports the required standby function if power management is critical to the application.
