- Integrated enable and disable control capability
- Compact surface-mount design suitable for space-constrained applications
Applications
- General-purpose clock signal generation
- Digital system timing references
- Embedded controller clock sources
Procurement Notes
Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design requirements. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connectivity.
Selection Notes
Select this component when a precise 10.145 MHz clock source is required with low-voltage operation. The LVCMOS interface ensures compatibility with standard logic families. Consider the physical dimensions and leadless package type for integration into dense circuit boards where traditional through-hole or larger SMD packages are unsuitable.
Part Context
This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The suffix OE typically denotes specific packaging or configuration details within the manufacturer's lineup, distinguishing it from other variants like the PD suffix models.
Replacement Considerations
Direct substitutes include the 18QHTF21-10.145-PD, which shares the same frequency and package but may differ in voltage or suffix specifications. Verify functional equivalence regarding output logic and supply voltage before substitution.
