Oscillators 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 system design. Ensure the 4-SMD package footprint matches the PCB layout requirements. Check availability status as inventory levels may vary among distributors.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The 4.912 MHz frequency suits specific baud rate or clock division needs. Consider the compact 4-pin SMD form factor for space-constrained designs. Evaluate the standby feature if power efficiency during idle states is a priority for the application.

Oscillators Part Context

This part belongs to the 18QHTF series of standard oscillators from Mercury Electronic. The series typically offers various frequencies with LVCMOS outputs and low-voltage support. The 'PD' suffix likely indicates a specific pin configuration or packaging variant within the manufacturer's lineup. These components are commonly used in consumer electronics and industrial control systems.

Oscillators Replacement Considerations

Direct substitutes include other 4.912 MHz LVCMOS oscillators in 4-SMD packages with 1.8V supply ratings. Verify pinout compatibility and electrical specifications such as jitter and stability before substitution. Cross-reference with similar models from Mercury Electronics or other manufacturers offering equivalent timing solutions.
