Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm electrical characteristics and package type. Ensure compatibility with target voltage levels and load requirements before integration. Cross-reference part numbers with authorized distributors to validate authenticity and sourcing channels.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 11.059 MHz reference frequency. The small 2.0x1.6 mm footprint makes it suitable for space-constrained designs. Confirm that the LVCMOS output swing matches the input thresholds of the connected logic devices.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, designed for high-frequency stability in consumer and industrial electronics. The series typically offers various frequencies within a standardized small outline package format, supporting mass production needs for timing applications.

Replacement Considerations

Compatible substitutes include other 11.059 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and thermal specifications before substitution.
