Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB design guidelines to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this oscillator when a 33.868 MHz frequency is required alongside a 1.8V supply constraint. The LVCMOS output is suitable for direct interfacing with standard logic families. Consider the 2.0x1.6mm package size for tight spatial limitations. Evaluate the standby feature if power efficiency is critical for the application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD no-lead package. The series typically provides options for different supply voltages and output types. The 'PD' suffix likely indicates a specific pin configuration or lead-free status as per manufacturer coding standards.

Oscillators Replacement Considerations

Direct substitutes include other 33.868 MHz XO components with LVCMOS output and 1.8V operation in a 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as phase noise and jitter before substitution.
