Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronic documentation to confirm exact electrical characteristics and pinout configuration. Ensure the 1.8V supply requirement aligns with system design constraints before procurement. Cross-reference the 4-SMD package dimensions with PCB layout specifications to ensure mechanical fit.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise 15.55 MHz timing. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small 2.0x1.6 mm footprint for space-constrained designs requiring surface-mount assembly.

Oscillators Part Context
