• Data communication interfaces requiring stable clock frequencies

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB silkscreen and solder mask specifications to guarantee proper assembly and electrical connection.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 49.2032 MHz frequency. Consider the enable/disable pin requirement if power cycling or standby modes are part of the system architecture. Evaluate the small 2.0x1.6mm form factor against available board space constraints compared to larger oscillator packages.

Part Context
