Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and output configuration. Confirm that the 1.8V supply requirement matches the target system design. Check package tolerance against PCB footprint specifications. Ensure the LVCMOS output level is compatible with downstream logic gates. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS signaling is required. The 2.0x1.6 mm package suits space-constrained layouts. Consider the power-down feature if dynamic power management is necessary. Verify that the 80.3 MHz frequency aligns with system clock requirements. Evaluate thermal performance within the specified operating range.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The series includes various frequencies and voltage options.
