Oscillators Procurement Notes
Verify the specific suffix against official datasheets to confirm electrical characteristics and package dimensions. Ensure the enable/disable functionality aligns with system power requirements. Confirm supply voltage tolerance matches the target application's 1.8V rail stability before integration.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Verify that the 4-SMD footprint fits the PCB layout constraints compared to larger packages.
Oscillators Part Context
Mercury Electronics Ind. Co. Ltd specializes in frequency control products, including quartz crystals and oscillators. The 18QHTF series represents their line of surface-mount crystal oscillators designed for modern electronics requiring stable clock signals in compact form factors.
Oscillators Replacement Considerations
Check for direct substitutes from Mercury Electronics with identical frequency and package. Other manufacturers may offer compatible LVCMOS oscillators but require verification of pinout and voltage compatibility.
