Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the 4-SMD footprint matches the PCB layout specifications before finalizing the purchase order.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The 2.304 MHz frequency is suitable for baud rate generation or specific clock division needs. Consider the small 4-SMD form factor for space-constrained designs. Verify that the standby feature meets power efficiency goals for portable or battery-operated devices.
