Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint constraints. Ensure the 1.8V supply voltage matches your target circuit's power rail specifications to guarantee proper operation and avoid damage.
Selection Notes
Select this component when a precise 69.1909 MHz reference is required with low power consumption capabilities. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the 50 ppm stability rating for applications requiring moderate frequency accuracy. The integrated power-down feature makes it suitable for battery-operated devices needing efficient sleep modes.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequency options within a standardized small form factor. These components are designed for high-volume manufacturing and reliable performance in consumer and industrial electronics. The manufacturer specializes in quartz-based frequency control solutions.
Replacement Considerations
Direct substitutes must match the 69.1909 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar SMD oscillators if availability is an issue.
