Oscillators Procurement Notes

Verify the specific suffix 'MHZ' against the manufacturer's official part number guide to ensure correct frequency tolerance and pinout configuration. Confirm that the 3.2 mm x 2.50 mm package dimensions match the design footprint requirements. Ensure the selected variant supports the required 3.3 V supply voltage and enable/disable control signals for the target application.

Oscillators Selection Notes

Select this component for designs requiring a 50 MHz clock source with CMOS or TTL output compatibility. Consider the 3.3 V operating voltage and the physical constraints of the 4-SMD no-lead package. Verify that the enable/disable feature aligns with system power management strategies. Ensure the frequency stability meets the timing requirements of the connected digital circuits.

Oscillators Part Context

This oscillator belongs to the ISM97 series from ILSI, which provides standard clock solutions in small form factors.
