Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable joint formation during assembly.

Oscillators Selection Notes

Select this component when a precise 38.68 MHz timing source is required within a low-voltage 1.8V environment. The choice is appropriate for applications necessitating a small form factor due to the 2.0x1.6 mm package size. Consider the LVCMOS output level if interfacing directly with standard digital logic families without additional level shifting. Evaluate the standby feature if power management is a critical design constraint for the end product.
