Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the host system's power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 34.816 MHz clock source is required for low-voltage digital circuits. The integrated enable pin allows for dynamic power control, making it suitable for battery-operated devices. Consider the small form factor for space-constrained designs requiring reliable timing signals without excessive board area consumption.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same physical package. The series provides standardized LVCMOS outputs for compatibility with common microcontrollers and FPGAs. The 'OE' suffix typically indicates specific ordering or packaging variations defined by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes must match the 34.816 MHz frequency, 1.8V operation, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before swapping components to ensure circuit stability.
