Oscillators Procurement Notes
Verify the exact frequency specification against the manufacturer datasheet, as similar part numbers may differ slightly. Confirm the operating temperature range and load capacitance requirements match the target circuit design. Ensure the 1.8V supply voltage aligns with the system power rails before procurement.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a specific 24.577 MHz frequency. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor if board space is limited compared to larger oscillator packages.
Oscillators Part Context
This model belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage crystal oscillators. The series typically offers standard frequencies with LVCMOS outputs. Mercury Electronic Ind. Co., Ltd. is a recognized manufacturer of quartz crystals and frequency control products based in Taiwan.
Oscillators Replacement Considerations
Direct replacements must match the 24.577 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify that any substitute part maintains the same enable/disable functionality and physical dimensions to ensure mechanical fit.
