Procurement Notes
Verify the specific suffix (OE) against official datasheets to confirm enable functionality and voltage levels. Ensure the operating temperature range meets system requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm package dimensions match PCB footprint specifications before integration.
Selection Notes
Select this component when a low-voltage 1.8V LVCMOS oscillator is required. The enable feature supports power-sensitive designs. Verify that the 7.65 MHz frequency aligns with system clock needs. Consider the small form factor for space-constrained layouts. Check load capacitance requirements if driving external loads.
Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronic, a supplier specializing in quartz crystals and oscillators. The series typically offers various frequencies and voltage options. Mercury has decades of experience in frequency control products, providing reliable timing solutions for industrial and consumer electronics markets.
Replacement Considerations
Direct substitutes must match the 7.65 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify electrical parameters such as jitter and stability. Check pinout compatibility for the enable pin. Consult manufacturer cross-reference lists for approved alternatives.
