Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for reflow soldering profiles to guarantee assembly reliability.
Selection Notes
Select this component when a precise 13.2531 MHz clock source is required for low-voltage digital circuits. The integrated enable pin makes it suitable for battery-operated devices requiring power conservation. Consider the small 2.0x1.6mm footprint if space is limited on the printed circuit board. Validate compatibility with LVCMOS input thresholds of the receiving logic gates.
Part Context
This oscillator belongs to the QHTF series from Mercury Electronics, designed for high-reliability timing applications. The series offers various frequencies within a standardized surface-mount form factor. These components are engineered to meet industry standards for frequency stability and phase noise performance in modern electronic assemblies.
Replacement Considerations
Direct substitutes include other 13.2531 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Verify that alternative parts support the same 1.8V operating voltage and enable pin configuration. Ensure equivalent electrical specifications regarding frequency stability and output drive strength.
