Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance against project requirements before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD package dimensions fit within the allocated PCB footprint. Cross-reference the manufacturer's latest datasheet to confirm current availability and shipping terms directly from Mercury Electronic Ind. Co., Ltd.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The inclusion of a power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. The small form factor supports high-density board layouts. Ensure the application does not require spread spectrum or advanced jitter specifications beyond standard XO performance.
