Oscillators Procurement Notes

Verify the specific operating voltage and load capacitance requirements against your circuit design before procurement. Confirm that the 3.3V supply rail matches the component's electrical specifications. Ensure the PCB layout accommodates the 2.0x1.6 mm package dimensions and solder pad configuration to guarantee reliable assembly and performance.

Oscillators Selection Notes

Select this component when a 22.04 MHz clock signal is required within a minimal physical envelope. The LVCMOS output simplifies interfacing with microcontrollers and FPGAs without additional level shifting. The enable pin allows for dynamic power control, making it suitable for battery-operated devices where energy efficiency is critical during idle states.

Oscillators Part Context

This oscillator belongs to Mercury Electronics' high-frequency control product line, which includes crystals, filters, and oscillators. The company has specialized in timing components since 1973, focusing on quartz-based solutions for various industrial and commercial applications. This model represents their standard XO series optimized for modern surface-mount manufacturing processes.

Oscillators Replacement Considerations

Direct substitutes include other 22.04 MHz LVCMOS oscillators in 2.0x1.6 mm packages from manufacturers such as SiTime or Epson. Verify pin compatibility and electrical parameters like phase noise and jitter before substitution. Equivalent parts must support the same 3.3V supply and enable logic polarity to ensure seamless integration.
