• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 15.8 MHz reference is required alongside strict space limitations due to its small 2.0x1.6 mm form factor. Consider the 1.8V operating voltage and LVCMOS interface compatibility with your target microcontroller or FPGA. The inclusion of a power-down mode makes it suitable for battery-operated applications where standby current reduction is critical.

Oscillators Part Context
