The 18QHTF21-100.100-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 100.1 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and pinout configuration. Ensure that the selected variant matches the required operating temperature range and load capacitance specifications for the target application circuit. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Select this component when a low-voltage 1.8V supply is available and LVCMOS outputs are required. Consider the 4-SMD No Lead footprint constraints during PCB layout. Evaluate the need for the enable/disable functionality if power management or clock gating is necessary within the system architecture compared to continuous oscillation alternatives.
This model belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The product line focuses on quartz-based oscillators for various industrial and consumer electronics applications. Mercury Electronics has established itself as a supplier of frequency control products since 1973, offering crystals, filters, and oscillators.
