Procurement Notes
Verify the exact part number suffix against official Mercury Electronics documentation to confirm voltage and package specifications. Ensure compatibility with target board layout regarding the 2.0x1.6mm footprint. Cross-reference datasheet parameters for operating temperature range and load capacitance requirements before finalizing procurement decisions.
Selection Notes
Select this oscillator when a 64.22 MHz frequency is required with LVCMOS outputs. Consider the 1.8V supply constraint and enable/disable feature for power-sensitive designs. Evaluate the 4-SMD package size against available PCB real estate. Confirm that the operating temperature range meets environmental conditions.
Part Context
This component belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. These oscillators are designed for high reliability in consumer and industrial applications requiring precise timing.
Replacement Considerations
Direct substitutes include other 64.22 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD 2.0x1.6mm footprints. Verify electrical parameters such as jitter and phase noise match original requirements. Check manufacturer availability and lead times for alternative sources.
