Oscillators Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure compatibility with required tolerance and temperature range specifications. Confirm that the 1.8V supply requirement aligns with the target system design before procurement. Cross-reference the 4-SMD no lead package dimensions with PCB footprint libraries to prevent assembly errors during manufacturing integration.

Oscillators Selection Notes

Select this component when a precise 30.135 MHz reference is required for 1.8V logic systems. Consider the enable/disable feature if power management is critical. Ensure the application environment supports the specified operating temperature range and that the LVCMOS output swing is compatible with downstream input thresholds.

Oscillators Part Context

This part belongs to the QHTF series of standard oscillators from Mercury Electronics. The series offers various frequencies and voltage options.
