Oscillators Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to ensure correct electrical characteristics and package type. Confirm that the OE suffix aligns with the required enable/disable functionality and voltage specifications before finalizing procurement orders.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a specific 17.142838 MHz frequency reference. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs where standard SMD packages are preferred over through-hole alternatives.
Oscillators Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series offers various standard frequencies and voltage options within a consistent small outline package format designed for modern surface-mount assembly processes.
Oscillators Replacement Considerations
Direct substitutes must match the 17.142838 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and enable/disable signal polarity with alternative manufacturers before integration.
