Procurement Notes
Verify the specific datasheet version directly from Mercury Electronic Ind., Co., Ltd. to confirm electrical tolerances and pinout configurations. Ensure the ordering suffix matches the required frequency and package type. Cross-reference official documentation against distributor listings to validate authenticity and technical accuracy before procurement.
Selection Notes
Select this component when a precise 66.667 MHz clock source is required within space-constrained designs. The 1.8V supply requirement dictates compatibility with low-voltage digital logic families. The enable pin allows for dynamic power control, making it suitable for battery-operated or energy-efficient systems requiring periodic clock activation.
Part Context
This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers standard frequency options with LVCMOS outputs. The 'OE' suffix indicates the specific variant with enable capabilities. This family targets applications needing reliable timing signals in small form factors.
Replacement Considerations
Direct substitutes must match the 66.667 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify that any alternative part includes the enable/disable function if power management is critical. Check footprint compatibility and pin assignment alignment before integration.
